Avril Lavigne flashes the flesh in her new video What The Hell.
The pop star shows off her sexy svelte body wearing just her underwear in the clip.
The new music video, which features the disclaimer 'viewer discretion is advised', sees the Sk8r Boi singer stealing and eventually crashing a cab.
She then interrupts a playground basketball game before buying some new clothes.
In the video Avril is also seen lying in bed with a man who looks suspiciously like her real life boyfriend Brody Jenner.
