While celebrating her 22nd birthday at the posh Hyde club in Los Angeles, with her husband Deryck
Whibley, the punk-rocker Avril Lavigne showed off, once again, that deep inside, she is not a people's person.

As she undertook a drastic makeover during the past few months and got herself some very sweet deals with some of the biggest modeling agencies, the rocker could still use some help in the manners department. As she left the nightclub, she became so annoyed with the paparazzi that were waiting outside for her that she repeatedly insulted them and then, seeing that it did no good for her cause, spat in their face.

As she was walking towards her SUV, surrounded by her entourage, Lavigne told one of the paparazzi, 'Hey, f**khead, come here', leaned over and spat right on his camera lens. After she got into the car, eyewitnesses say, she rolled down the window and again made full display of secret weapon, by hitting another cameraman in full face.

She then started to giggle, then laugh hysterically, while screaming at the top of her lungs 'Bitch!', an insult probably hurled at the entire crowd that gathered on the street to see the spectacle.

The assaulted reporters were working for the celebrity agency TMZ and, to Avril's disadvantage, they have it all on tape and plan to file charges against her. If they do that, the singer with spitting skills could face a fine of up to $2,000 or six months in jail or both at the same time.
