Justin Bieber was attacked in a Toronto nightclub early Friday morning. Bieber left the VIP section to chat up some pretty girls on the dance floor when another clubgoer charged at him. The assailant's effort to tackle Bieber failed and security quickly pulled the guy off. The attacker was tossed out the club. Police were never called, although Bieber did have a gold chain stolen during the fiasco. It's unknown at this point what sparked the attack. Just last month, Bieber was involved in a fight outside a New York club.
