Erin go bragh! St. Patrick's Day is just around the corner, and we're getting a head start on the festivities by revealing some of the lucky Hollywood ladies that you may not have known are Irish.

Megan Fox is so proud of her Irish heritage that she told Esquire in January 2013 about one particular mythical Irish creature she bought into. "I like believing. I believe in all of these Irish myths, like leprechauns," she said. "Not the pot of gold, not the Lucky Charms leprechauns. But maybe was there something in the traditional sense? I believe that this stuff came from somewhere other than people's imaginations. ... We should all believe in leprechauns."

And mama-to-be Olivia Wilde is so proud of her Irish heritage that she even has dual citizenship in Ireland as well as the United States! Another brunette beauty that's proud of her background is Demi Lovato. In November 2012 the singer revealed on Twitter that she has Irish roots, writing, "I found out that I am Irish, Hispanic, Native American, Portuguese and Jewish!!!"

But the "Let It Go" singer isn't the only one. Some of Tinseltown's brightest stars have the luck of the Irish, including Mandy Moore and Zooey Deschanel.

The "New Girl" star, dishing to the L.A. Times back in 2003, said that due to her Irish and French ancestry she thinks that her looks make her "a natural Goth."
