Mothers and fathers raising their children in the glitz and glamour of the Hollywood spotlight have little ones to think about. All unattached progenitors are protective of themselves and their broods when they venture out into the wide world of dating, but celeb moms and pops have to be even more selective and careful. If the wrong person is allowed into their inner circles, their privacy could be lost forever. For this reason, many celeb moms and dads make their lovers sign Non-Disclosure Agreements (NDAs). What does this mean, exactly? According to Business.com, “A Non-Disclosure Agreement is a legally enforceable, written contract by which one or more parties agree not to disclose confidential information that they have shared with each other.”

Famous parents aren't the only ones who often choose to protect themselves and their families by ensuring those near and dear to them aren't allowed to spill the beans without facing a huge penalty. In fact, Justin Bieber makes anyone entering his elaborate mansion in Calabasas, California sign a Liability Waiver and Release. What happens if they violate it in any way? They face the possibility of being sued for up to $5 million. That’s no joke. TMZ has reported that the documents in question stipulate that after leaving his home Bieber’s guests are not allowed to discuss the “physical health, or the philosophical, spiritual or other views or characteristics” of him or any of his other guests.

If Justin and other celebs without kids have to watch their backs, it only makes sense that famous parents would need to do the same. Read on for 15 smart celeb moms and dads who make their lovers sign NDAs.

15 Jennifer Lopez

Jennifer Lopez has never been mum about her romantic escapades. In fact, she seems to enjoy public displays of affection. Over the years, she's been linked to Ben Affleck, P Diddy, Casper Smart (one of her backup dancers) and, most recently, MLB great Aaron Rodriguez. She's also tied the knot three different times. The first time she was married it was to actor and producer Ojani Noa, the second to actor and choreographer Cris Judd, and the third to singer Marc Anthony, with whom she shares her adorable twins, Max and Emme.

It has been reported that "within weeks" of getting back together with Smart after a brief split, Lopez made him sign an NDA. After her past troubles with jilted lovers, we can't really say we blame her.

Her first husband, Noa, famously attempted to cash in on his time spent married to Jenny from the Block. He claimed to have footage that would damage her career, reveal some embarrassing secrets she was keeping and prove that her family had a gambling problem. Noa also threatened to publish a tell-all book, and has said that he has "unfinished business" with Lopez. He never did get rich by defaming his former flame, and instead had to pay $545,000 for violating their confidentiality agreement.

14 Lamar Odom

Lamar Odom became a household name after he spent time as Khloe Kardashian's main man. The couple's marriage and life as newlyweds was all documented and aired on the E! network. The world fell in love with the pair, and were heartbroken when their fairytale romance didn't last.

During his marriage to Khloe, and since the split, Odom has struggled with addiction. It was widely reported that the former NBA star suffered a drug overdose at the Las Vegas Bunny Ranch. Since, the owner of the establishment has claimed that before Odom would engage with any of the ranch's "employees," he was sure that everyone present in the building at the time had signed an NDA.

The father-of-three once shared, "Negative publicity makes people forget your best times. Being humbled has been a part of my life for a long time. Respect goes a long way when you carry yourself a certain way and show manners when you first meet someone. I've got a winner mentality, the mentality of a champion." We hope there are happier days ahead for Lamar.

13 Scott Disick 

Oh, Scott. He's one reality star most people love to hate. Despite his current relationship with a much younger woman, Sofia Richie, he isn't cool with the fact that his baby mama, Kourtney Kardashian, has a young lover of her own. When Kourt shared the news with Disick that she was in a relationship with 24-year-old model Younes Benjima on a recent episode of Keeping Up With the Kardashians, he lost his sh**, and, according to Kourtney, became "very aggressive."

It has been reported that when Scott and Kourtney aren't on again or making a baby together, he makes his other lovers give up their phones and sign NDAs before getting busy.

The question some may be asking is, "Is Scott really a big enough celebrity to go to extreme lengths to protect his privacy? Does anyone really care who he canoodles with?" We'll allow him to answer this question. The self-proclaimed Lord Disick once famously stated on the reality show that made him kinda, sorta famous, "I'm a big star. I don't need to be dealing with you peasants." Enough said. If anyone is willing to make out with him after that, giving up their phones and signing a piece of paper is the least of their worries.

12 Britney Spears

Pop star and mother-of-two Britney Spears has had her share of relationship struggles over the years. She and Justin Timberlake were so adorable together, but eventually, their messy break-up became gossip magazine fodder. She then suffered a very public meltdown after impulsively getting married in Las Vegas.

In recent years, Spears seems to be in a much better place. It also appears that she has learned from her past mistakes, and has realized that keeping her private life private is a good way to go. According to TMZ, Spears wouldn't even go out with her current beau Charlie Ebersol until he signed an NDA. Allegedly, Ebersol didn't mind signing on the dotted line if it meant getting to go out with the "Slumber Party" singer. How romantic.

Speaking about romance, Spears has shared, "With love, you should just go ahead and take the risk of getting hurt...because love is an amazing feeling."

11 Justin Timberlake

Justin Timberlake and his lady love Jessica Biel are just the cutest, so it came as quite a shock to their fans when photos of Timberlake getting cozy with another woman were published in the Irish magazine, Heat. The mag's headline accompanying pics of Justin being affectionate with an unidentified female in a Paris nightclub read, "Justin Timberlake gets flirty with another woman, It is not his wife!" and "The flirty photos that rocked Justin and Jessica's marriage."

It's no secret that Jess and Justin made the honored guests at their wedding sign NDAs before attending. They even insisted on Justin's good pal Jimmy Fallon signing one. Rumors have circulated that the real facts behind the photos published in the magazine were squelched due to an NDA Justin procured before things went too far.

Heat magazine's publisher, Bauer Media Group, did retract the article's claims and issued an apology after Timberlake filed a defamation claim against them. They stated, "The article was based on an unfounded report regarding Justin Timberlake's alleged behavior at a club following a performance in Paris...the Defendant regrets any embarrassment caused to the couple and unreservedly apologizes to them." So where's the brunette beauty in the photos? She's not talking, and we think we know why. Possibly due to an NDA she signed?

10 Tom Cruise

Tom Cruise and Katie Holmes started off hot and heavy, but Katie eventually realized she had married a somewhat unstable fellow and prepared to make her escape. It has been reported that her plot to leave her A-list hubby was fraught with secret cell phones and whispered meetings. However, when it came time for them to split, Cruise was sure to get the last word.

The actor had Katie sign an NDA that forbade her from speaking about their marriage or Tom's heavy involvement in the religion of Scientology. She was also barred from dating anyone publically for at least five years after the divorce was final. Geez. That's not at all overly controlling. We wonder why Katie would ever want out of a relationship with such a rational, kind gentleman.

Tom once wisely stated, "I have respect for what other people believe. What I believe in my own life is that it's a search for how I can do things better, whether it's being a better man or a better father or finding ways to improve myself." He just doesn't want anyone talking about what exactly he believes.

9 Charlie Sheen

It's no secret that Charlie Sheen is a womanizer. His scandalous behavior has been chronicled multiple times in the tabloids over the years, and it's safe to say he's had his fair share of sexual encounters.

Sheen has five children: Sam, Lola, Cassandra, Bob and Max with three of his ex-lovers Denise Richards, Paula Profit and Brooke Mueller respectively. Reportedly, the actor has admitted to having his partners sign NDAs before sleeping with him. The penalty for breaking the agreement? A fine upwards of 100k. Maybe Charlie wants to make sure his kids are protected, or maybe he wants to protect himself.

In an interview with Playboy, Sheen revealed, "We take phones and purses at my house, and people have to sign sh**. I'm not living in the Pentagon, but I've been burned enough to take precautions." Ladies may want to think twice before getting between the sheets with Sheen, but he begs to differ, and once admitted, "Here's the good news. If I realize that I'm insane, then I'm okay with it. I'm not dangerous insane." Well, that's comforting.

8 Kylie Jenner

Even though it has never been officially confirmed, everyone in the world is pretty darn sure that Kylie Jenner is expecting her first child with her boyfriend Travis Scott. The Instagram sensation and lip mogul hasn't posted any full body pics lately, and has been pretty absent from social media altogether since the holidays.

It has been reported that Kylie isn't just making her love interests sign NDAs, but anyone who wants to see her at all. According to a source, Kylie will only welcome guests if they first go through a "security check." This includes walking through a metal detector, being frisked, handing over cell phones and signing a $10 million confidentiality agreement before they are welcomed into her presence.

A source told Radar Online, "She is currently hiding in Kris's home, where half of the windows have been covered to prevent any photos of her." Why so secretive? The insider also dished, "She just really wants to make sure that there are no secret cameras being smuggled in."

7 Bill Cosby

Bill Cosby was one of the most beloved comedians and sitcom stars of the 80s and 90s. His reputation as a lovable family man has been tainted in recent years due to dozens of women coming forward and accusing him of sexually assaulting them. The cases went to court, and, although the judge in the case declared a mistrial after the jury couldn't come to a unanimous decision, Cosby was charged with three counts of aggravated indecent assault against Andrea Constand, a former basketball staffer at Temple University.

During the trial, one of Cosby's alleged victims claimed he made her sign an NDA. It is unclear how many of the women he slept with over the years were bound by a secret contract to keep them from speaking up.

The father-of-five once admitted, "What kept me out of trouble is going right to the edge and then...thinking that my mother would be embarrassed, and that I didn't want to embarrass her, and that my father would be embarrassed, and I just didn't want to do that to my family."

6 Rob Kardashian

The latest scandal to involve the infamous reality television brother Rob Kardashian and his former fiancé Blac Chyna involves racy pics and a broken NDA. Kardashian posted photos of Chyna that were in poor taste on Twitter and she was quick to get a restraining order and call him on the carpet in public for being a major d-bag.

Rob's baby mama shared on Good Morning America that she was "devastated" by his uncouth behavior. Reportedly, when the ABC network reached out to the Kardashian family for a comment about the interview, Kim Kardashian's reps responded with an NDA from June of 2016 that Chyna had signed. In the agreement, she reportedly said she would refrain from revealing any details about the Kardashian family.

Allegedly, Chyna agreed to sign the document as a condition of appearing on Keeping Up With the Kardashians. According to a copy of the agreement referenced by People magazine, Dream's mama "shall not at any time disclose, publicly or privately, any information which is in any way, fashion or manner related to, associated with or connected to the Kardashian family, Jenner family, Disick family, West family and/or their personal relationships, their business activities, plans, operations, finances or employees." This family does not mess around.

5 Chris Brown

Chris Brown has a sordid past in the love department. Just ask Rihanna what kind of a boyfriend he is. It's likely the answer she'll give wouldn't be a kind one. Despite his not-so-great track record, Brown doesn't have any problem getting ladies to hang with him. However, they do so at their own risk.

According to one groupie, she caught Brown's eye at a party, but he left the dirty work up to his staff. Allegedly, his security approached her to see if she was interested in hanging with the musician for the night. When she agreed, she was asked to sign an NDA on the spot before she and Breezy could exchange pleasantries.

The father-of-one can be pretty dreamy when he waxes poetic. He once mused, "Loving is doing anything for them, thinking about them constantly and being able to spend your whole life with that person. Liking somebody is just like, 'Okay, I like them because of this, this and this, but I don't know if I'm ready to be in love with them.'" Awe.

4 Drake

While nothing has been officially confirmed, rumors are currently swirling that rapper Drake has a baby on the way! If the gossip is true, Instagram model Layla Lace is pregnant with the "Fake Love" singer's child, as is p*rn star Sophie Brussaux.

According to Drake's reps, the claims these women are making are totally false. Speaking about Brussaux, a rep told TMZ, "This woman has a very questionable background. She has admitted to having multiple relationships. We understand she may have problems getting into the United States. She's one of many women claiming he got them pregnant."

Is it possible that Drake is a serial baby daddy, but women are staying quiet because he makes them sign NDAs before they can fraternize with him? Actually, yes. A few years back, a woman broke the terms of an NDA she had signed before going all the way with Drake, and...let's just say...we wish she wouldn't have. The details she revealed were a bit more than anyone needed to know, but she also dished that entering the star's house was like "walking into the White House" due to the amount of security. She had to hand over her cell phone, and had her driver's license photocopied. She was also asked to sign an NDA.

3 Mariah Carey

Mariah Carey has beautiful twins with her ex-husband Nick Cannon. The two parted ways amicably, and still spend time together for the sake of their little ones, but it seems the terms of their divorce were a bit one-sided.

According to reports, after the split, Cannon signed a confidentiality agreement that barred him from speaking in public about the end of their union. If he did, he faced pretty steep financial penalties. As for Mariah, she's free to talk until she's blue in the face about why things didn't work out between them. The two have moved on to other relationships. No word on whether or not the "We Belong Together" singer is requiring her current love interests to sign iron-clad documents before they are allowed to canoodle with her.

Carey once shared, "Trust is not very easy for me at all. I want to be a trusting person, but I've been bruised so many times--not to sound woe-is-me about my life." Maybe her struggle to trust those she loves is the reason she feels she must protect herself with NDAs.

2 Ben Affleck

It broke the hearts of pretty much everyone when it was reported that Ben Affleck had broken Jennifer Garner's heart. There are some people you just don't mess with, and Garner is one of them. Despite the fact that couple had a seemingly perfect marriage and family, the news broke that they were getting a divorce soon after it was reported that Affleck was having an affair with his kids' nanny. Allegedly, the Justice League 2 actor had his lady on the side sign an NDA, but that didn't keep his secret affair from becoming very public knowledge.

The Oscar winner has recently been spotted out and about with television producer Lindsay Shookus. No word on whether or not he asked her to sign on the dotted line before they became an item.

Speaking about his very public split from Garner, Affleck has said, "It never seems like a great time to have your privacy invaded. Obviously, this is a particularly hard time."

1 Bow Wow

Bow Wow may look sweet, but he doesn't mess around when it comes to who he allows into his inner circle. The rapper shared on Facebook that potential lovers must sign an NDA and leave their phones with security if they want the chance to romance him.

The star has one daughter, Shai Moss, with his ex, Erica Mena. After his little angel was born, Bow Wow denied he was a new father and even spoke out publicly against websites that reported the exciting news that he and his lady had welcomed a new addition. He later explained, "I waited too long to tell y'all the truth because I was nervous about how y'all would look at me. Y'all know everyone makes a big deal out of everything I do. I wanted to be the 1st n let y'all know the real."

Sounds like this dude likes to keep his private life private. Hence, the extreme security measures he takes to ensure his lady loves aren't revealing tidbits about his life behind closed doors to the public.
