Christina Aguilera Loses Her Cool

Christina Aguilera lost her cool the other night at Hollywood hot spot Mood. The songbird and her fiance, Jordan Bratman, were enjoying themselves when "a fight almost broke out," said a witness.

"I looked over and Christina was standing on the couch and she was yelling at some guy: 'Get out! Get out!' Her security was holding her back and forcing the guy to leave. It caused a big scene." Aguilera's rep said: "There was a drunk and unruly person at the club threatening Christina and he was removed."
