Actor sisters Dakota and Elle Fanning look so much alike—and have since childhood—that they've even played the same character. In 2001's I Am Sam, Elle, who's four years younger, played Dakota's character at an earlier age.

Chris and Scott Evans not only take after each other, they also chose the same career. Scott, who's two years Chris's junior, had his big break on One Life to Live and currently plays Oliver on Grace and Frankie. He and his Marvel actor brother are super close and have always been supportive of each other, as you can see from this throwback picture Scott posted of his big brother coming to see him in his school musical.

Chloe and Halle Bailey, who record their music under the name Chloe x Halle, are so similar-looking that they convincingly play twins on the show grown-ish. This has proven to be confusing to fans who just assume that the sisters are also the exact same age, but, in fact, there's two years' difference between them!

Beyoncé and Solange are such big stars that there can't be many people who don't already know who they are. But if the siblings, who are separated by five years, weren't famous for their own musical endeavors, they'd probably get mistaken for twins more often.

It's not just their features that make it a dead giveaway that Jaden and Willow Smith are siblings—it's also the daring sense of style that they both share. Jaden is two years older, but, if we didn't know that, we'd guess that they were twins.

Brother/sister pair Christian and Neve Campbell are the spitting image of each other, and they also share a love of performing.
