Guess Which Movie Stars Are Related to U.S. Presidents!

In honor of Presidents Day, we're taking a look at some of your favorite celebrities who you may not have realized are related to U.S. presidents!

We know that George Clooney is interested in politics, but it could be because it's in his blood. Ancestry.com revealed that "The Monuments Men" star is a half first cousin five times removed of Abraham Lincoln.

Honest Abe is not only related to Clooney but also to another distant descendant who is also a Hollywood actor. Tom Hanks is Lincoln's third cousin four generations removed. The "Captain Philips" star even paid tribute to his kin during President Obama's 2009 Inauguration celebration."Abe Lincoln was a quiet and a melancholy man, but when he spoke of democracy this is what he said, 'as I would not be a slave, I would not be a master, this expresses my idea of democracy.'"

Lincoln may have two A-list celebrities in his lineage, but the current leader of the free world, President Barack Obama, also has a famous face in his. The New England Historic Genealogical Society found that Brad Pitt and the president are ninth cousins, all thanks to a relative in common who lived in Virginia in the 1760s.

It might not seem as if Brangelina needs any more family members, but the same study found that Brad Pitt's longtime partner, Angelina Jolie, is related to a powerful woman in politics. Check out this video to see who it is, and tune in to "The Insider" tonight for the latest in entertainment news.
