Justin Bieber shows his tough side when he pretends to be up a skateboarder in front of friend Miley Cyrus on last night's episode of Punk'd!

"The Biebes" explained to viewers before the prank that he would be starting a brawl with some actors, while Miley thought she was going to punk the pop star. "She's not punking me because that's not possible. I can't be punked," Justin exclaimed.

We loved watching the "Baby" singer push two of the skateboarders to the ground, after kicking one in the stomach while he was down.
