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.

Check out the hilarious video above!
