It happens all the time. You're binge watching your favorite show on Netflix or having a movie marathon when there's an actor on screen that you know you've seen before somewhere else, but you can't place them. Yes, your déjà vu could be due to the fact you've seen the actor's face as another character on a different show or movie, but there's also a strong chance you recognize them because they strong resemble a another celeb sibling.

Yup, folks, nepotism is alive and well in Hollywood, sometimes it's just a little bit undercover. Turns out there are tons of famous brothers and sisters kickin' around Tinsel Town, they just keep it on the DL most of the time. We're not totally sure why, but we do know one thing: talent isn't definitely in some people's DNA, because it runs wild through the veins of these celebs.
