Fraternal or identical, brother or sister — these celebrities have one thing in common: They all share a birthday with a special sibling.
Hunter and Scarlett Johansson
Even though they're twins, there's one big difference between these two: a whole 12 inches! ScarJo is just 5-foot-3-inches tall while her brother Hunter is 6-foot-3-inches tall. While he's acted in the past, Hunter hasn't done a ton of entertainment projects recently — instead, he's worked in politics, both on President Obama's 2008 campaign and as a community organizer in Manhattan.
Kiefer and Rachel Sutherland
This pair of siblings decided to go into the entertainment industry together, but while Kiefer is an actor, Rachel works as a post-production supervisor.
Michael and Ashton Kutcher
We all know it's Ashton Kutcher on the right, but did you know he has a fraternal twin brother? Michael Kutcher, who has cerebral palsy and underwent a heart transplant as a 13-year-old, works at a sales company and does motivational speaking for young folks with disabilities.
Tia and Tamera Mowry
These gals are so similar looking that they literally starred in a show called Sister, Sister, beloved by anyone who grew up in the '90s. These days, Tamera co-hosts the talk show The Real while Tia has recurring roles on Rosewood and Mistresses.
Dylan and Cole Sprouse
You may not instantly recognize this young pair, but any kid in your family could tell you these two are none other than Dylan and Cole Sprouse, a.k.a. the twins from The Suite Life of Zack & Cody. Since their successful Disney series ended in 2008, the two have applied themselves to their studies, graduating together in 2015 from the Gallatin School of Individualized Study at New York University.
Angel and Aaron Carter
You may know Aaron as the younger brother of Backstreet Boy Nick Carter, but did you know he also has a twin sister? While her brothers both opted for musical careers, Angel Carter pursued modeling instead.
Jason and Jeremy London
Both of these identical twin brothers have starred in beloved films and TV shows, with Jason playing Randall in the cult favorite Dazed and Confused and Jeremy appearing in Mallrats, 7th Heaven and Party of Five.
Aaron and Shawn Ashmore
These two look so much alike, you can barely tell 'em apart! Bonus: Both Canadian fellows are actors, with Aaron appearing on Smallville and Shawn starring in multiple successful X-Men films.
Mary-Kate and Ashley Olsen
Okay, so this one isn't exactly surprising — these two are probably the most famous twins on the planet! Since their days as Tanner on Full House, among many other roles, the pair has flourished in the fashion world with their label The Row.
Jenna Bush Hager and Barbara Pierce Bush
You may know their names, but did you know they're fraternal twins? Jenna has served as a correspondent on NBC Nightly News as well as the editor-at-large of Southern Living magazine, while Barbara has devoted her energies to philanthropy, working with the Human Rights Campaign in pursuit of gay marriage legalization.
Joel and Benji Madden
As teenagers, this famous pair of rockers formed the band Good Charlotte back in 1996. These days, Benji is married to actress Cameron Diaz and serves as a judge on The Voice Australia, whereas his identical twin brother Joel is married to Nicole Richie and continues to produce music.
Eva and Joy Green
Born two minutes prior to her sister Joy, actress Eva Green says she is very different from her twin. While Eva has pursued an acting career since her early twenties, Joy has never wanted to act and instead prefers to raise horses with her husband in Normandy.
Marissa and Giovanni Ribisi
While her brother Giovanni is known for his roles in Saving Private Ryan, That Thing You Do! and Ted, Marissa is known for her fashion line Whitley Kros.
Rami and Sami Malek
Rami, a rising television star, plays the lead role in the acclaimed drama Mr. Robot, while his slightly younger identical twin brother Sami works as a teacher in Los Angeles.
Tiki and Ronde Barber
Imagine having not one, but two pro athletes in your family. While Tiki is now an on-air personality, he previously played for the New York Giants as a running back, while his brother Ronde spent 6 years as a cornerback for the Tampa Bay Buccaneers.
Parker and Christopher Posey
Moviegoers love this actress for her roles in Best in Show, The House of Yes and other cult favorites, but they may not realize she has a twin. Parker's brother Christopher works as a lawyer.
Jon and Dan Heder
You may know Jon Heder from his breakout role as the title character in Napoleon Dynamite, but you probably didn't know that his twin brother Dan also works in entertainment — both as an actor and as a visual effects artist.
Gisele and Gabriela Bundchen
Seen here with their sister Rafaela (L), Brazilian supermodel Gisele and her twin Gabriela (R) clearly share the same incredible genes.
Nicholas Brendan and Kelly Donovan
Not only are both of these brothers in the entertainment industry, but Kelly Donovan actually acted as a stand-in for his brother on Buffy: The Vampire Slayer a few times.
Vin Diesel and Paul Vincent
This Fast & Furious star indeed has a fraternal twin, Paul Vincent, who works as a film editor.
Charlotte and Samantha Ronson
While these two look totally different, they're both extremely hip: Charlotte is a fashion designer and Samantha is a DJ.
Here's a little known fact about the King of Rock and Roll: He was a twin. Born in Tulepo, Mississippi, on January 8, 1935, Presley was born 35 minutes after his identical twin brother, who was sadly delivered stillborn.
