Is talent something you're born with? If these famous families are any indication, it looks like stardom is indeed genetic. The celebs you didn't know were siblings might surprise even the most intense IMDB trivia fans. Honestly, it's kind of amazing how stars are so connected.

From television and movie stars to models and singers, these famous siblings are the embodiment of #lifegoals. (Well, for people who aspire to be famous, anyway). It looks like many people are happy to follow in the footsteps of siblings when it comes to career choices, and these stars are no different.

Plus, it's fun to compare your own sibling relationships to the stars'. If you were a world-famous model or actor, how would you feel about a younger sibling pursuing a similar path? Thrilled? Peeved? It's fun to image the inner workings of these brother-sister connections from a distance. Like, what were the Blooms fighting about when they were tots? Legos? Pizza slices? The TV channel? And we imagine that a least a few of them have to maintain some sort of sibling rivalry, especially when it comes to roles. Hmm, I wonder if Kate and Rooney Mara were ever neck and neck to play the same character...

As much as you thought you know the ins and outs of the celebrity world, some of these famous relations will surely be a surprise. Did you know Ariana Grande's brother is a popular reality show and YouTube personality, or that both the Delevingne sisters are models-turned-actresses? It's bananas. And don't even get me started on the Hemsworth brothers of which there are three — I repeat, three. Read on to learn how your favorite entertainers are basically all related.
