Lil Jon committed a serious party foul on New Year's Eve at Prive, a nightclub within the Planet Hollywood Resort and Casino in Las Vegas. Avril Lavigne was slated to call out the 10-second countdown, but when it was time to ring in the new year, the rapper, who was hired to DJ the shebang, swiped the mic and took the honors.

Attendees say that Lavigne was visibly upset when Lil Jon stole her moment. "I wanted to do the countdown," the singer said. Lavigne calmed herself after a bottle of Dom Perignon champagne was brought to her table.
