Check out Avril Lavigne covering the classic ballad Tik Tok by Ke$ha during her appearance at the Radio 1 Live Lounge with Fearne Cotton (above)!
LOLz! Yeah, it's kind of HIGHlarious how seriously she's singing the words as she reads them off the paper, right?
You don't need to pretend that you don't know the lyrics, bb! They're permanently etched into EVERYONE'S brainz!
That being said, she does a pretty nice job! Well done, gurl!
