Justin Bieber is know for being quite the prankster, but he may have met his match: Willow Smith.

When Willow was asked about the in-concert prank Justin pulled on her in a recent interview, she decided to clear something up: She pulled a prank on Justin first!

"I was coming offstage, and I see the 'one less lonely girl'. I had my little camera and I was like, 'I'll be paparazzi!'" Willow dishes. "So I come out and I'm taking pictures of him and her, and he was smiling at me with the widest eyes. When he got offstage he was like, 'you're crazy!' and I was like, 'don't mess with me.'"

Unfortunately for Willow, Justin got the last laugh when he jumped onstage with a pair of drumsticks while Willow was whipping her hair back and forth.

Still, their prank war is far from over. "I'll get him back when he's 50," Willow says.

Who do you pulled the better prank: Justin or Willow? Do you think Willow will actually wait until Justin's 50 to pull another prank?
