Avril Lavigne Performs Ke$ha's 'Tik Tok' (VIDEO)

Avril Lavigne swung by BBC 1 Radio's Live Lounge to promote her new album Goodbye Lullabye, her first in four years.

In an effort to rejuvenate her bad-girl image, the early aughts Canadian break out paid homage to another party-animal pop star, Ke$ha. However, Avril gives the song a heavy Dave Matthews treatment, and acoustically the song loses much of its devil-may-care attitude. She also performed "What The Hell?" the album's lead single.

The Live Lounge has become a nexus for cover songs with Bruno Mars attempting Katy Perry's "California Girls" and Taylor Swift trying her hand at Coldplay. Take a look at the most recent installment below.
