Zooey Deschanel and Emily Deschanel

OK, maybe they share a couple similar features (though not signature bangs), but that doesn't necessarily mean they can pass for siblings. Besties? Sure. Sisters? Not so much.

Ariana Grande and Frankie Grande

Beanie Feldstein and Jonah Hill

This sibling duo doesn't look much alike, but they are indeed brother and sister. While we generally know him as "Jonah Hill," his name is actually Jonah Hill Feldstein — he shares his last name with his younger sister, Booksmart actress Beanie Feldstein.
