It turns out more than a few people can say they've been tattooed by Harley Quinn.
Margot Robbie revealed her penchant for amateur tattooing on Friday's Tonight Show. It's a hobby that began when she purchased a tattoo gun on eBay. (Yes, that's a thing you can do.)
Now, she practices on her friends, including Cara Delevingne. She even asked a few pals to let her tattoo them in lieu of a birthday gift.
Gotta be honest: her "girl holding a balloon" is pretty cute.
