Justin Theroux & Younger Brother Sebastian Step Out in New York City—Plus, More Pics of Hot Siblings!

Jennifer Aniston's fiancé taking a stroll with his baby bro inspired us to further explore this celebs-with-attractive-brothers-and-sisters situation

Two hot men in leather? Yes, please.

Jennifer Aniston's hunky husband-to-be, Justin Theroux, stepped out today with his younger bro Sebastian, giving us double the eye candy and twice the reason to swoon.

The coordinated duo—both rocked leather jackets with tight skinny jeans—took a stroll together in SoHo, and seeing them sparked an idea: Why not put together a gallery of a bunch of hot celebs with equally hot siblings?!

So we did.
