Canadian bad girl Avril Lavigne celebrated her 22nd birthday in less-than-grand style by spitting on photographers outside a Hollywood hotspot on Wednesday, TMZ reports.

It marks the second time this week that Lavigne has had a run-in with the paparazzi -- she reportedly spat on a photographer's camera lens while visiting the Hyde Lounge Tuesday.

Prior to the spitting incident Wednesday, Lavigne also verbally berated autograph seekers outside, and wrote "f*** you" on the photos presented to her.

Video of the incident can be seen on TMZ's website here.
