Hmmm. . . Justin the Bieber is at it again. Thought the boy has turned a good boy after several cries in front of the camera professing he has turned a new leaf.

Not so, he went with Kyle Jenna to Playboy event and Playboy Model Sarah Harris accused him of grabbing her boobs during a chat. "He grabbed my boob! And it was my instant reaction to just backhand him across the face," says Sarah.

Hmmm... no comment, I hope this is not publicity stunt.
