Being a twin is arguably a huge characteristic – one which most people tend to know about before they even know anything about you. “Oh, he’s the twin, right?”“Did you hear about the twins?”“I can never tell those two apart!”But what happens when one of the wombmate duo gains international fame, and the other is less famous? The twin trait tends to take the backseat, which is why there are a bunch of celebrities you’re familiar with, whom you’ll be surprised to find out are actually part of a birthday duo.
1. Ashton Kutcher, most recently known for his role in Two and a Half Men, and his fraternal twin Michael who suffers from cerebral palsy, are practically best buddies. 
2. Brazilian supermodel Gisele Bundchen is one of a beautiful fraternal duo along with twin sibling Patricia, and they are just two of five gorgeous Bundchen sisters! 3. Canadian alternative rock idol Alanis Morisette has a twin brother, Wade, who’s also in the music industry, creating yoga-influenced indie rock albums. 4. Napoleon Dynamite star Jon Heder has an uncannily identical twin brother called Dan. Unlike his clone, Dan keeps behind the scenes, working as an animator. 5. Kiefer Sutherland has a twin sister who also works behind the camera, as a post-production supervisor. Luckily for their mom, they were born much less than 24 hours apart (Get it? Get it?) – seven minutes to be exact. 6. Paul Vincent is Vin Diesel’s twin brother. Who’d have thought the famous Fast and Furious star had a twin! Fraternal twin Paul reportedly also works in the film industry as an editor. 7. Parker Posey and her twin brother Christopher took completely different career paths. She’s acts in indie films and he works as an attorney. 8. Bond girl Eva Green and her fraternal twin sister Joy also made quite different life choices. Joy, who studied business, rears horses in Normandy, where she lives with her husband who’s an Italian count. 9. Although Leslie, Linda Hamilton’s identical twin sister, has a completely different job from her famous actress sibling (she actually works as a nurse!), Leslie still got her moment of fame back in 1991 when she stepped in as Linda’s body double in Terminator 2: Judgment Day. 10.
