['Lil Jon] was deejaying a countdown party at Prive, where [Avril] Lavigne was slated to call the countdown. But before the stroke of midnight, onlookers saw 'Lil Jon "grab his own mike and steal the show" from Lavigne by "holding his own coundown." The pop princess was said to be "visibly upset" and clung to her hubby Deryck Whibley, crying "I wanted to do the countdown!" Only when servers brought out Dom Perignon did she calm down.
