In the world of celebrity starlets, there seem to be very few secrets. After all, it seems that thanks to the paparazzi and social media, we know more and more about our favorite celebrities than we ever did before. Celebs take to their Twitter, Facebook, Instagram, and SnapChat accounts to keep their fans constantly in the loop about their every move.  They show us what they're wearing and what they're eating and where they're going and who they're with, and we love it all!

But what happens when a celebrity wants to keep something private after they've been known to share so much publicly? Any woman who has ever been pregnant and had a baby knows what an exciting time in your life it is. And many women like to keep that information private for as long as possible. Some like to wait those first three months just to make sure everything is OK, while others just like to keep their good news to themselves until it's no longer something that can be kept a secret.

Hollywood is full of celebrities who desperately tried to keep their pregnancies a secret but failed miserably when eagle-eyed paparazzi and even well-meaning friends revealed the truth!

15 Blake Lively Gets Caught On Set

Blake Lively and hunky hubby Ryan Reynolds have made it no secret that they want to have lots of kids. Blake's first daughter James was just 8 months old when she first began filming the movie 'The Shallows' where she was constantly in a bikini, looking ah-mazing! However, eagle-eyed fans and paparazzi photographers couldn't help but notice the gorgeous actress looking a little different when she arrived months later for re-shoots.

The actress was photographed on set wearing a full piece wetsuit and constantly covering her midsection with a towel or robe. Many were quick to point on that the actress, who had yet to confirm any pregnancy, was indeed expecting baby #2. Those people were correct and Lively and Reynolds welcomed their second daughter, Ines, was born on September 30, 2016.

14 Kim Kardashian's Not-So-Secret Surrogacy

Kim Kardashian embraced pregnancy with her first two children, 4-year-old North and 2-year-old Saint, but when it came time to have baby #3, the reality star decided she wanted to keep things a little more private.

That's because the most famous of the Kardashian sisters, who suffered through severe complications with her first two children including preeclampsia and placenta accreta, had hired a gestational carrier to carry her third child. Knowing it could be potentially harmful to herself and the baby to carry a third child, Kardashian, and husband Kanye West hired someone to do the heavy lifting for them.

While the couple tried to keep their new pregnancy a secret, 'sources' were quick to tell publications like PEOPLE and TMZ that baby West #3 was on the way. They even revealed that her surrogate was an African American, college-educated woman in her mid-twenties who had been married for five years and was the mother of two. So much for keeping that pregnancy a secret.

Kim and Kanye welcomed their third child, daughter Chicago West on January 15.

13 Pink's Friend Spills The Beans On Twitter

It's hard to keep secrets when you're an international recording artist. It's even harder when your friends have loose lips!

Singer Pink had been doing a great job of keeping her pregnancy with first daughter, Willow, under wraps until someone literally announced the news on social media.

“Hey, Pink, I’m sooooo happy for you lady!!! Congrats on baby!!” Good Day L.A. co-host Jillian Barberie Reynolds wrote on her Twitter page, announcing the news before it was made public. “Ps. You know your man whispered it to us at dinner. See I CAN keep a secret!!”

Reynolds clearly didn't know what 'keeping a secret' meant because Pink hadn't made her news public yet. I'm assuming Reynolds got an earful over the tweet because she followed it up writing another post that was somewhat apologetic.

“So @pink hasn’t confirmed. My bad!! Hubby says that I must have been tipsy that night cuz that’s not what Carey said!! My complete apologies.” The singer then confirmed the news for herself during an appearance on The Ellen DeGeneres show.

She was obviously more careful with her second pregnancy, as her Instagram announcement that showed her with a very large baby belly was a surprise to all her fans.

12 Kirsten Dunst - "I Need A Baby!"

If you want to keep your pregnancy a secret, perhaps you shouldn't give interviews talking about how much you want to have a baby!

Former child star turned bona fide movie star Kirsten Dunst has been engaged to her Fargo co-star Jesse Plemmons since last year, and now it seems they've wasted no time adding to their family! While the actress hasn't confirmed her big news, paparazzi have caught friends of the actress eagerly rubbing her stomach and she's taken to wearing a lot of baggy clothing.

The actress revealed in an interview with Marie Claire over the summer that she was definitely ready for a baby of her own.

"I wasn't one of those 'I need a baby!' people until my goddaughter was born," she told the mag. "I love her so much. That love is just like... you can't experience that unless you have a kid."

"I put her to bed last night and she woke up this morning and said to her mom, 'Where's Kiki?' I just love that love. That’s what I want," she added.

Looks like she's going to get her wish, and soon!

11 Eva Longoria - Suspicious Extra Pounds

The worst part about being pregnant is that awful period of time where you don't really look pregnant, just like you've gained some weight. That's only worse for some women if you're using fertility treatments because often times those will cause weight gain before a woman even conceives!

Eva Longoria was forced to defend herself against paparazzi pictures that showed her with a fuller figure and accusing the actress of gaining weight amid pregnancy rumors. Some even speculated that her weight gain was a result of using IVF to help her conceive. Finally, in December of 2017, she admitted that she is expecting her first child, a son.

It's definitely hard to keep something like a baby a secret when your body is constantly being scrutinized by the press and the public.

10 Khloe Kardashian - The Worst-Kept Secret

Khloe Kardashian had probably one of the worst-kept secret pregnancies in the history of secret pregnancies. Rumours began swirling months ago that the reality star was expecting her first child with her NBA beau Tristan Thompson. Fans were elated that Koko was finally going to have a baby, knowing how much she always wanted to be a mom herself. But for a family who shares everything about themselves with the public, people were surprised that she was keeping mum on this big news.

Kardashian stopped wearing the form-fitting clothes she was known for wearing to show off her 'revenge body,' instead opting for more casual outfits and A-line dresses. She even began posting photos on her social media that pictured her from the chest up or where she had items strategically placed in front of her midsection.

Naturally this only fuelled the rumors further, and finally, on December 20, 2017, she finally confirmed what we'd known all along. The Good American designer posted a picture of her growing baby bump and explained why she tried to hide her pregnancy from her fans.

"I know we've been keeping this quiet but we wanted to enjoy this with our family and close friends as long as we could privately. To enjoy our first precious moments just us."

Well, it was a good try!

9 Joanna Gaines Couldn't Keep Chip Quiet

Fans of HGTV's smash show 'Fixer Upper' were saddened just a few months ago when the show's stars, Chip and Joanna Gaines announced that the current fifth season would be the last. That sadness quickly turned to speculation with many wondering why the parents of four would pull the plug on their show when it is so popular?

While some suggested the couple wanted more privacy for their four children, Drake, 12, Ella, 10, Duke, 9, and Emmie, 7, others were positive the couple were clearing their schedule to make room for baby #5. Chip himself hinted that another baby was on the way for the couple during an interview about the end of their home reno show.

“We had four babies right before the show started, and then we’ve had zero babies since the show started,” Chip told ABC affiliate KTRK. “For me, I’m really excited to go back and try to maybe… try to make some more babies.” Joanna just laughed off Chip's suggestion of more babies, perhaps trying to keep her pregnancy quiet. Anyone who watches the couple on television knows that Chip doesn't do quiet!

8 Kerry Washington - No One Knew For 4 Months

Like the rest of us, sometimes celebrities just want to keep their pregnancies private for as long as possible. That's not so easy when you're on one of the biggest television shows on TV today, not to mention being the star!

Kerry Washington tried for about four months to keep her pregnancy a secret all while filming her hit show Scandal. Unfortunately, we all know that a baby bump can't be told what to do, and soon enough the show was trying to find any and every way to keep Washington's bump hidden because Olivia Pope was not pregnant!

Washington revealed she carried a lot of big purses, stood behind a lot of lamps and used a lot of props to hide her growing baby belly.

Her daughter, Isabelle Amarachi Asomugha was born on April 13, 2014.

7 Reese Witherspoon's 3rd Mystery Baby

Reese Witherspoon was already a mom of two when she and Ryan Phillippe split up. The couple shares a daughter and son together, but it seems that Witherspoon wasn't done having kids. Witherspoon remarried high powered CAA agent husband Jim Toth in 2011 and it wasn't long before pregnancy rumors began following the actress.

Witherspoon tried to hide her growing baby bump behind baggy clothes and A-line dresses, but after making it known in previous interviews that, “I would love to have more kids, my children are the best part of my day,” fans and the media quickly began to suggest the actress had a bun in the oven.

Friends close to the actress began confirming to multiple news outlets that she and Toth were expecting their first child together when she was just 12 weeks pregnant. So much for keeping it a secret!

The couple's son, Tennessee James Toth was born on September 27, 2012.

6 Eva Mendes Shocked The World

I have to hand it to Eva Mendes because she is one A-list actress who knows how to keep her personal life locked down! The actress, who has been in a long-term relationship with Ryan Gosling has had not one, but two very low key pregnancies. The couple shocked the world when it was revealed they became parents for the first time, and then shocked us all once again when their second daughter was born.

Unfortunately for the couple, loose-lipped sources leaked news of Mendes's pregnancy despite the uber private couple making any sort of announcement.

The news the couple was expecting again broke in mid-April 2016, and the couple welcomed second daughter Amada Lee Gosling just two weeks later on April 29th. I guess they didn't fail miserably at keeping their big baby news a secret! So close!

5 Kylie Jenner - Still A Secret!

Oh, Kylie! Rumours have been circulating for months that the youngest of the Kar/Jenner clan is expecting her first child with new boyfriend, rapper Travis Scott. While Kylie has seemingly gone underground and no family member has confirmed the rumor, her social media feed has been very telling.

Kylie Jenner's Instagram feed used to be littered with pictures of the LipKit founder in various stages of undress, showing off her assets and perfectly toned body. As the pregnancy rumors began to pick up steam, the pictures she posted were much more modest, showing the reality star wearing big, baggy clothes or simply just photos of her face.

Perhaps the most telling is the fact that Jenner has been absent from almost all Kar/Jenner festivities over the past few months, and her recent ad campaign with her sisters for Calvin Klein has her posing with her stomach always covered. Sources close to the family say that Jenner is simply looking for a bit of privacy and wants to keep her pregnancy as low key as possible. She might be a part of the wrong family for that!

4 Kate Winslet Tried To Keep It On The DL

Some actresses may want to keep their pregnancies hidden for reasons other than personal - sometimes it's for professional reasons. Kate Winslet was in the midst of filming the movie Divergent when she was pregnant with her third child, as well as the period drama Little Chaos.

The actress wanted to keep her pregnancy a secret because she didn't want to be treated any differently. ''I just didn't want people to be making a fuss over me. When women are pregnant, it doesn't mean you stop doing things ... you just get on with it, so that's what I did,' the actress said about trying to hide her pregnancy. Unfortunately for Kate, her growing stomach betrayed her. Soon enough the actress's costumes for both her roles had to be refitted to accommodate her growing baby belly. She even had to don a corset for her role in Little Chaos.

Her son, Bear Blaze was born on December 7, 2013.

3 Jessica Simpson Couldn't Hide The Bump

Jessica Simpson is one of Hollywood's most gorgeous moms, but she's also had a few weight struggles in the past. Still, that didn't stop the paparazzi and the public from speculating about both her pregnancies. The singer and actress confirmed her first pregnancy with daughter Maxwell Drew at Halloween, posting a picture of herself and her sizeable bump on Twitter dressed as a mummy with the caption, "It's true. I am going to be mummy." Everyone pretty much knew it already.

The retail giant also attempted to hide her second pregnancy, which happened when little Maxi was just 7 months old, by wearing big baggy clothes and using those signature large purses to cover her baby bump.

Maybe it was because she had just signed a lucrative deal with Weight Watchers that she didn't want to confirm her pregnancy, but she wasn't doing a good job of hiding it.

Finally, she confirmed via social media once again that she was expecting her second baby, surprising absolutely no one.

2 Megan Fox Gets Pregnant After Her Split From Bryan

Megan Fox and Brian Austin Green have always been pretty private about their lives and family together. While they both will post the odd photo of the children they share, neither of them offer up too much information about their kids.

The couple, who married in 2010 are parents of two sons, Noah and Bodhi. Sadly the couple split and announced their separation in August of 2015. Clearly, the split wasn't permanent however because it wasn't long before baby #3 was on the way! Fox and Green kept the pregnancy on the down low, but Fox's promotional obligations for her movie 'Teenage Mutant Ninja Turtles: Out of the Shadows' meant her pregnancy news was quickly going to be out of the shadows!

The actress appeared at CinemaCon in Las Vegas in April to promote the family-friendly flick and her bump was on clear display. While Fox may have tried to keep her baby news a secret, the bump gives it away every time!

Fox and Green's son Journey River Green was born on August 4, 2016.

1 Jennifer Garner Couldn't Hide From The Cameras

Back when Jennifer Garner was one half of famous Hollywood couple Bennifer, she endured more than her fair share of rumors about herself. One particular rumor back in 2011 quickly began to spread after the actress, who was already mom to then 5-year-old Violet and 2-year-old Seraphina, was spotted out wearing baggy clothes. Naturally, fans of the actress as well as all the entertainment news outlets began to suggest that Garner and husband Ben Affleck were expecting their third baby. Despite many denials by Garner and her team the actress, she was a favorite of the paparazzi who photographed the actress and her obvious baby belly daily. It's no surprise the actress tried to deny the news. At the time she was working almost non stop having just wrapped a handful of movies as she began to film new ones. Perhaps she just didn't want her work to be jeopardized? Unfortunately, she was no longer able to hide her obvious pregnancy. The couple's third child, Samuel Garner Affleck was born on February 27, 2012.
