Between Mary-Kate and Ashley Olsen, Tia and Tamera Mowry, Dylan and Cole Sprouse, and Phil and Lil DeVille, Hollywood is no stranger to putting twins in the spotlight. But, not every twin pair is destined to dazzle us on screen.
From red carpet dates to casual co-stars, these siblings always have each other's backs. Here's a list of 14 celebrities who you may not have known have a twin cheering them on from the sidelines!
1. Vin Diesel and Paul Vincent
Vin Diesel's fraternal twin brother, Paul, is known to shy away from the spotlight, but earlier this year the actor shared a picture of Paul standing next to his late co-star and best friend, Paul Walker. The caption read:
Pablo and my mother would have deep conversations... she claimed, that it was no accident that this on-screen duo has come to define brotherhood in Our millennium.
You see... the other guy in the photo is also named Paul... and although they look more alike, he is actually my twin brother.
2. Scarlett and Hunter Johansson
ScarJo's twin brother and frequent red carpet date, Hunter, is more than just a pretty face. He's also very politically minded and even worked as a community organizer on Barack Obama's campaign for re-election.
3. Ashton and Michael Kutcher
Unlike his brother Ashton, Michael lives in Iowa with his son. Being born with a mild form of Cerebral Palsy, he works as a spokesman and motivational speaker for Reaching For the Stars, which gives money towards the research and prevention of Cerebral Palsy.
4. Jon and Dan Heder
Lucky for us, there are two talented Heder men working in Hollywood. While Jon's work takes him in front of the camera, Dan's is on the production end. Napoleon Dynamite's identical twin is an animator and is known for his work on 2006's Monster House.
5. Alanis and Wade Morissette
Like his twin sister Alanis, Wade Morisette is also in the music industry. Wade is a kirtan and indie pop-rock musician, yoga instructor, therapist, and author who has had features published in Yoga Journal and Macleans Magazine.
6. Kiefer and Rachel Sutherland
Kiefer Sutherland's twin sister Rachel might not be an actress, but she still has a major hand in making sure the industry is running. She is a production manager who has worked on projects like Rookie Blue and Saving Hope.
7. Giovanni and Marissa Ribisi
You might recognize Marissa Ribisi from her work in movies like Dazed and Confused and Pleasantville, but her acting career has been a little slower since marrying musician Beck in 2004 and raising their two children.
8. Linda Hamilton and Leslie Hamilton Gearren
Everyone knows Linda Hamilton from Terminator, but you probably also got a glimpse of her identical twin sister, Leslie, who acted as her stand-in for some scenes!
9. Brittany and Cynthia Daniel
This blonde pair made their start as actresses on Sweet Valley High, but after the show was canceled Cynthia quit her fast path to stardom to become a photographer. Brittany kept up with acting and has been in movies like White Chicks and Joe Dirt.
10. Rami and Sami Malek
A lot of you might not know that the Mr. Robot and Twilight actor has an equally handsome twin named Sami, who is a teacher in Los Angeles.
11. Gisele and Patricia Bündchen
Although both girls are gorgeous, Gisele's fraternal twin Patricia gave up the runway and instead acts as her sister's manager and spokeswoman.
12. Eva and Joy Green
Eva Green has admitted that she and her twin sister, Joy, can be a bit competitive, so I guess it's a good thing that she has no interest in testing out an acting career. Instead she studied business, rides horses, and reportedly married an Italian count.
13. Efren Ramirez and Carlos Ramirez
Another Napoleon Dynamite cast member with an identical twin is none other that Pedro's Efren Ramirez! I guess if we wanted to we could have two Pedros and two Napoleons, which sounds like a pretty good movie to me. Double the tots!
14. Parker and Christopher Posey
Parker Posey might be known as the Queen of Indie, but her twin brother Christopher's career has him practicing law in Atlanta.
