Showbiz is full of famous family pairs like siblings Joan and John Cusack or parent-child duos like Jon Voigt and Angelina Jolie. These are the celebrity kids we've watched grow up to be bombshells and handsome young men. But Hollywood is full of secrets--like these complicated family trees--and chances are you had no idea these celebrities were related.
Sure, some of these stars probably got the acting bug from their Hollywood family members, like Lord of the Rings actor Sean Astin and his mom, Patty Duke, or SNL alum Jason Sudeikis and his uncle, Cheers star George Wendt. But some leading men and ladies, like Stanley Tucci, married into a family of actors.
Hollywood stars aside, we still can't get over how crazy it would be to be related to a celebrity or even royalty! A very famous sister duo just happened to be distant cousins of King Edward III and Kate Middleton herself! Imagine a family dinner where you're seated across from the Duke and Duchess of Cambridge. Now that's a reunion you just couldn't miss!
Whether they came together by birth or marriage, there's no denying this bunch is full of star power.
