Secret Siblings? 18 Unrelated Sets of Celebrities Who Could Pass for Brother and Sister

Solange and Orlando Jones Beyonce's little sister and the former 7 Up spokesman may not actually be related, but they look so much alike that if Jones ever needs someone to have his back, he should be able to call his "sister" Solange to throw down in a fight. Tom Hiddleston and Katy Perry He's best known as the bad guy from the movie Thor, and she's a pop music sensation, but these two should definitely "Roar" together. Terrence Howard and Eva Marcille The Best Man actor and famous fashion model resemble each other so much that if one day it were to come out that they were related it would shock no one. Julia Stiles and Ansel Elgort The actress and actor share a similar story of rising to fame as teens. However, they also eerily seem to share the same face! Mischa Barton and Elijah Wood If Wood's character Frodo from the film Lord of the Rings ever needed a twin sister, actress Mischa Barton should be the only person to fill the role. Gabrielle Union and Gabriel Casseus Not only do NBA star Dwyane Wade's actress/fiancee and the Black Hawk Down actor share a similar name, but these two could definitely pass for brother and sister. Michael Cera and Laura Carmichael The Superbad actor and the Downtown Abbey actress look more related that your average set of fraternal twins. Bethenny Frankel and Michael Jackson We all know the King of Pop changed his face significantly with plastic surgery, but from the looks of things, he and Frankel (the reality TV star) may have shared the same doctor. Fergie and Bret Michaels She's a pop music star, and he rose to fame as a rock star. But even though they're not actually related, there should be a Bret Michaels/Fergie/Black Eyed Peas mashup at some point, based on their striking resemblance. Ellen DeGeneres and Owen Wilson The talk show host and the Wedding Crashers actor seem like long-lost siblings from another life. Both are famous, funny and look just alike! Melissa Rivers and Steven Tyler This would definitely be a case of a much older brother and younger sister. One could even argue that the Aerosmith rock star looks like he could have fathered comedian Joan Rivers' daughter. The two do look alike -- there's no argument there. Derek Luke and Tika Sumpter The actor and actress have already shared the screen together on the film Sparkle. But they also look like they share a set of parents as well. Felicia Pearson and Jadakiss On TV's The Wire, Pearson is best known for playing one of the most intimidating characters who happens to share a name with one of the most famous rappers: Snoop. But the actress actually looks like she may be related to a different well-known rapper: Jadakiss. Bow Wow and Lil Mama These two definitely have more in common than the fact that they both had "Lil" in their names at some point of their careers and that they're both rappers. Seeing that both of them are double-threat entertainers (music and acting), it would not be out of the question to see them playing brother and sister in a movie. KD Aubert and AJ Aubert and AJ are both known for hosting shows on cable music channels (MTV and BET respectively). And upon a quick glance, you'd think that hosting just runs in the family. Rosario Dawson and Rick Gonzalez As two of the most prominent Hispanic actors/actresses out there, this pair looks like they could be hermana and hermano. Khloe Kardashian and Elvis Presley OK, they never lived in the same time period. However, if the man often referred to as the King of Rock and Roll had lived in the present day, he could without question replace Rob Kardashian as the reality TV star's brother -- and the world just might believe it Shaunie O'Neal and Shannon Brown She's a basketball wife (or former basketball wife), and he's a basketball player. These two are only distantly linked through O'Neal's ex-husband, Shaquille, who like Brown won championships for the NBA's Los Angeles Lakers.
