WARNING: Strong language in video

Avril Lavigne is known for her angsty music, but she lets her famously gorgeous hair down and has fun, showing off her silly side in her 'Rock N Roll' video. It meshes live action and comic book footage of Av in fatigues and cammo. She also kisses a girl (and she liked it).

If you ever doubted Av's status a bada--, she proves it here, battling critters, creatures and a dog that drives drunk.

There's also girl-on-girl smooch between her and Danica McKellar, who played Winnie in 'The Wonder Years' and looks as though she hasn't aged a day.

Private Lavigne eventually reunites with her guitar and battles a bear with a shark's head. Rawr!

'Titanic' star Billy Zane also has a cameo that takes flight.

Our crush on Avril waned a little last year. It's elevated to full blown love again, thanks to this vid.
