Twins are celebrities by their own right.  Just ask any parent of infant twins - the questions, the attention, the infamy that follows multiples, particularly when they're infants, it can get a little overwhelming.  Perhaps this draw to the limelight is somehow connected to celebrities who are twins, or the multiples being born into famous families.

As children, people know who in their social group is a twin, usually because they're all in the same schools or the same social groups.  When people grow up this becomes a whole lot less apparent.  Some twins seek the shine of the spotlight whereas others prefer being in the background in the cool shade.

Around 90 percent of multiple births are twin births, which is why we all know of so many more twins than higher order multiples - they're so much more common. Around three percent of births are twins, with two thirds of twins being fraternal and only one in three as identical - which explains why there aren't a whole lot of Hollywood doppelgangers hanging around, although there are a handful that we'll visit shortly.  Here are 15 pictures of celebrity twins and their soon to be famous multiple offspring that you didn't even know existed until right now!

15 George & Amal Clooney's Twins

It wasn't too long ago that life time silver fox bachelor George Clooney would have balked at the thought of being connected with anything cuter than his pet pig Max, but then things changed. Today George seems like a natural fit as a beaming father to nearly six month old infant girl/boy twins, named Ella and Alexander. Clooney proved that it isn't too late to teach an old dog new tricks when he married wife Amal back in 2014, at 53 years old. When asked about his thoughts on parenthood and fatherhood, Clooney has said, "Look, it's exciting, and we're really happy and really excited, and it's going to be an adventure. We've sort of embraced it all with arms wide open."

14 Ashton & Michael Kutcher

Ashton Kutcher is a natural born speaker, so it's not surprising that he has some eloquent words of support for his fraternal twin brother Michael. Ashton said, "I was born a twin and from the moment I came into this world I had to share it with someone. I shared every birthday, every Christmas, I shared my bedroom, I shared my clothes, I shared everything that I had in this world and I didn't know there was another way because I always had my twin brother with me." Ashton's brother was diagnosed with cerebral palsy when he was a child and endured a heart transplant when he was just 13 years old. Today Michael is a speaker and advocate for Reaching For The Stars, an organization that works towards gaining cerebral palsy funding.

13 Queen Bey's Hive

Everyone who has internet access has surely seen the epic maternity photos and the equally iconic photos of Beyoncé and her adorable boy/girl twins Rumi and Sir. While Beyoncé likes to pick and choose the most film friendly moments for both her and her brood, it appears that just five months after their birth the family is beginning to make a few smaller appearances in public as a family. The mom was photographed in Florida with grandma Knowles while holding baby Sir and was said to look every bit the proud and doting mom we all expected. While the magnificent posed photographs are fantastic to look at, it's still nice to see photos of parents doing what the rest of us are up to with our kin, but we're betting there isn't a photograph in existence of the Queen Bey holding anything as unfabulous as a dirty diaper.

12 Supermodel Super Twins

Some twins grow up with a complex that their sibling is the better looking twin, and this can't be easy to deal with when your twin is a bonafide supermodel. Gisele Bundchen grew up in Brazil alongside five sisters, one, Patricia, who is her fraternal twin sister. Gisele was born first, but that doesn't mean that she makes her little sister sit backstage at all of her VIP events. Patricia is often Gisele's plus one on the red carpet and does not shy away from showing her sis just how much she cares. Despite being a new mom, Gisele repaid the sisterly love by bringing her infant son Benjamin, along with football star husband Tom Brady for Patricia's wedding in 2010.

11 Brad & Angelina's Twins

Brad and Angelina were the ultimate celebrity couple - and people couldn't get enough of them. They're good looking, they're charitable, they have an expansive family, and they're even celebrated with their own media made moniker: Brangelina. Angelina, who has six children with Brad, is mother to twins Knox and Vivienne, who were born in Nice, France where their parents owned Chateau Miravel, a large estate and vineyard (as Hollywood power couples are prone to do). While things have been more than just shaky for the couple recently, they seem to have reached a custody agreement and certainly we'll be seeing a lot more of both parents spending time with their many children, including the nine year old twins.

10 Scarlett & Hunter Johansson

Both named after vibrant colours, these twins were both born to shine. These fraternal twins are often seen together on the red carpet, since she often selects him as her "plus one" for Hollywood affairs, but the acting scene isn't really his cup of tea (he tried out a movie role once with his sister back in the 1990's but didn't acquire the acting bug, it's the only film he's ever been in). Hunter is highly involved in politics and even worked with former president Barack Obama on his 2008 re-election campaign. Philanthropy seems to run in the family with the twins working together in 2014 when they hosted the Champions of Rockaway Hurricane Sandy Fundraiser in New York.

9 Mariah Carey's Twins

It's hard to believe that it's been more than six years since Mariah Carey and Nick Cannon had twins Moroccan and Monroe. The diva is a proud mom and often posts photos celebrating life with her twins. This year she posted plenty on Instagram about a very special birthday party for the two which featured pink and blue (the twins' favourite colours) and teddy bears. Anyone who was VIP enough to get included on the guest list was able to enjoy pastries from Rafi's Pastry and mini bouquets of pink roses as their own personal party favors from Ana's Secret Garden. Last summer Mariah wowed audiences by belting out a duet with her two smallest backup singers who may have a future of their own in the spotlight.

8 Alanis & Wade Morissette

You oughta know that this Canadian singer is twin B to her older brother Wade Imre Morissette, who is just a few minutes older with the shared birthday of June 1, 1974 as Geminis (which isn't so 'ironically' the astrological sign for twins).  While both have been drawn to music since childhood, it's little sis Alanis who has enjoyed much more commercial success.  Wade is employed as a yoga instructor and has been known to perform his own angst ridden kirtan Indie Rock, only his incorporates both English and Sanskrit chants.  Proving that the twin bond, even into adulthood, is a real thing, Alanis decided that she would name her son Ever Imre in a tribute to her bro.

7 Jennifer Lopez & Marc Anthony

Good parenting means being able to put aside your personal issues for the sake of your kids. This is something that divorced parents Jennifer Lopez and Marc Anthony have managed to do for their now nine year old twins, Max and Emme, and even celebrated together on their birthday. Of her role as a twin Mama, JLo wrote on Instagram, captioning below a collage of photos of her children, "I can't believe that it's nine years ago today that God entrusted me with the biggest blessings of my life...he finally sent me my beautiful twins, my babies, my love and my life in two lil human beings. I immediately felt bonded, protective, overwhelmed with emotion and like the luckiest woman on this earth. And I’ve felt that way every day since.”

6 The Robotic Brothers

Rami Malek is famous for his role on the hit show Mr. Robot (he's also lesser known for his role in the children's film Night At The Museum where he plays Ahkmenrah).  He also has an identical twin brother, Sami, and has made waves and been a part of numerous hit memes since the duo appeared on Jimmy Kimmel together.  Sami Malek, although every bit as good looking as his twin brother, isn't interested in acting.  Instead he works as a LA based school teacher.  In terms of 'typical' twin hijinks, Rami has admitted that he has posed as his brother before, but it was for a good cause. Mr. Robot bent the rules in real life and once performed a monologue for his brother in order to help him score a good grade that would allow him to graduate from university.

5 The Terminator Twins

Linda Hamilton became famous for her legendary muscular arms as she was able to properly kick butt and take names as a trailblazing female performer.  Her memorable portrayal of Sarah Connor in the Terminator franchise led the way for many future female actors, but maybe her successes are partially owed to her sister.  Terminator II: Judgement Day should have its name not just because it's a sequel, but also because it stars both twin Hamilton sisters.  Although Leslie Hamilton is a nurse by trade, she had her own moment in the sun when she was the body double for her identical twin sis Linda in the 1991 film.  When filming T2 Linda suffered permanent hearing loss in one ear after failing to use her ear plugs when shooting a gun in an elevator.

4 Madonna's Adopted Twins

Earlier this year Madonna decided to expand her family and adopted five year old twins, Estere and Stella.  Madonna has four other children, two of whom she adopted in 2008.  She met Estere and Stella over two years ago at Home for Hope and then it 'hit her' when she was spending time with them again on another trip.  Madge spoke to her children about adding to their family and then began the adoption process.  The not so Material Girl has said of her decision, "Sometimes I would just close my eyes and think, 'Why isn't my kitchen filled with dancing children?' I thought, 'What am I waiting for? Just do it.'"  Madonna says that while this took some acclimatization for all of the children, they're all adjusting very well to their bigger family.

3 Neil Patrick Harris & His Twins

As a parent of girl/boy twins who are just about the same age, I'll admit I have more than just a soft spot for twins Harper Grace and Gideon Scott.  NPH and his hubby David Burtka seem to have a laid back parenting style and are known for celebrating fun moments with their kids, most notably in some fantastically put together Halloween costumes that are always matching and on theme.  NPH and Burtka both donated their swimmers to two separate eggs (from an anonymous woman) and had them implanted into a surrogate.  To this day neither parent knows for sure which child has which father, but they both have suspicions.  Burtka told Wendy Williams that he believes that Harper is biologically his and Gideon belongs to NPH, however we don't think the couple is going to be booking DNA testing to find out one way or another seven years later.

2 Kiefer & Rachel Sutherland

Jack Bower, er I mean Kiefer Sutherland has a twin sister?  It's true - he's a twin.  People love to talk about the fact that Kiefer is son of known actor Donald Sutherland, but not about the existence of his twin sister Rachel.  While Rachel works in Hollywood, you aren't likely to see her on the silver screen or even from the comfort of your living room. Rachel works firmly behind the camera and is a television post production supervisor. Kiefer has said about growing up as a twin, "My mother made a point of allowing us to be different.  She didn't get into that cutie thing of wearing the same outfits.  We had a strong sense of our own identities."

1 Parker & Christopher Posey

Parker Posey plays a fantastic mean girl.  Best known for her roles in films like Dazed and Confused and Josie and the Pussycats. Posey has had a lengthy career as a working actress and says of her niche roles and successes, "I'm the character actor in Hollywood movies, the girl who has to be annoying so the guy can go to the other girl." Most people don't know that she has a twin brother, Christopher Parker.  Christopher works as an attorney.  The Posey twins were born two months premature on November 8, 1968 in Baltimore, Maryland.  In 2018, fans can see Parker star as Dr. Smith in the television series Lost in Space.  As for Christopher, he'll be in a court room somewhere doing his regular job like the rest of us regular folk.
