12 celebrities you didn't know are left-handed

Sunday 13th August marks International Left-Handers Day. (Yup, it's totally a thing. No, we're not lying.)
To commemorate this momentous occasion, we've set about uncovering the world's most famous left-handers. According to science (that's as specific as we can be), only 10% of the population are left-handed, but it seems as though the celebrity world is chockablock with left-handers. From the Biebs to J Law, here are the celebs living their best left-handed life...
Justin Bieber
That sweet music Justin Bieber makes? It's all down to that left hand of his...
"Basically when I started playing the guitar, I picked up a right-handed guitar. 'Cause that was all... my mom had a right-handed guitar in the house," Bieber told Nightline. "And picked it up and I picked it up left-handed. My mom would switch it the other way. And I would switch it right back to the other way and try to play. It was difficult because it's backwards. My mom, I think it was for my birthday, she bought me a left-handed guitar. And so ever since I was young I learned on a left-handed guitar."
Lady Gaga

Ever wondered why Mother Monster favours a left hand claw? Now you know.

The Slow Hands hitmaker is left-handed but plays guitar with his right hand. That's a whole lot of hands.
