Avril Lavigne's New Years Tantrum

Avril Lavigne saw in the New Year with an almighty tantrum, according to onlookers at her countdown party at a Las Vegas nightspot.

The moody singer hosted the New Year's Eve bash at Prive in Planet Hollywood Resort and Casino and reportedly had her heart set on doing the all-important countdown to midnight.

So Avril apparently flipped when rapper 'Lil Jon – who was DJ’ing the night - grabbed the mic as 2008 approached and stole her thunder.

The New York Post reports: “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. Her reps could not be reached.”

Better luck next year, Avril.
