Happy National Left Handers Day! 18 Celebs You Didn't Know Were Lefties

They say that left-handed people are more creative than their right-handed counterparts, and that totally makes sense—so many movie stars, artists and TV actors are lefties! Celebrate National Left Handers Day by keeping in mind celeb lefties like Justin Bieber, Sarah Jessica Parker, President Obama and more.

Even though her twin sister Ashley is a good ol' righty, Mary-Kate Olsen is not. And fun fact—you can usually tell which twin is which on old episodes of Full House by looking at which hand Michelle uses more dominantly.

Many Beliebers probably know everything there is to know about Justin Bieber, but do you think they know that he's a lefty? Probably.

Carrie Bradshaw was left-handed because Sarah Jessica Parker is a lefty in real life.

Ashley Tisdale is left-handed, which is a good thing because she now has a shiny new engagement ring to show off on her left ring finger!

Mom-to-be Danielle Jonas is a lefty. Let's hope Baby Jonas inherits dad's talent and mom's lefthandedness!

Hollywood elite like Nicole Kidman are proud members of the Lefties in Hollywood club.

One Direction's Niall Horan is different from his bandmates in that he's the only one from Ireland and the only one who is left-handed. Aww.

President Obama leads the country and also leads the pack of most successful lefties in America. Former President Clinton is a lefty, too!

We bet all lefties in the world are happy to have at least one thing in common with the gorgeous, talented, left-handed Angelina Jolie.

JLaw is a lefty, but when she shoots bow and arrows as Katniss in The Hunger Games, she does so as a righty. It's called acting, folks.

Julia Roberts is blessed with good looks, talent, and a dominant left hand.

Bruce Jenner is a lefty even though his daughters Kendall and Kylie are not. Guess the Kardashian genes were dominant with that one.

Anna Kendrick is an aca-perfect addition to our list of famous lefties.

Prince William is a lefty, which means that the chances of Prince George being a lefty are pretty up there.

Phoebe was the only left-handed friend on Friends, which makes sense since Lisa Kudrow is the only left-handed Friends cast member in real life.

Scarlett Johansson is many amazing things, a lefty being one of them.

Kate Hudson not only got her gorgeous looks and talent from her mom, Goldie Hawn—she inherited her lefty genes, too!

Jay McGuiness of The Wanted is the only lefty of the band, and also the funniest, the cutest, the most talented...the list goes on.
