(NEW YORK) -- Before super-producer Dr. Luke created hits for Katy Perry and Ke$ha, he worked with Avril Lavigne. So it's not so surprising that Avril would feel comfortable covering one of Dr. Luke's biggest hits of the past year for BBC's Radio 1 Live Lounge, a show that features artists doing acoustic covers of other performer's songs. Avril did an acoustic version of Ke$ha's smash hit Tik Tok for the show, and perfectly mimicked Ke$ha's half-rapping, half-singing delivery.
Avril's new CD, Goodbye Lullaby, is in stores now. She'll appear on The View on Wednesday, and on The Tonight Show with Jay Leno on Monday, March 14. On Tuesday, she'll be on Jimmy Kimmel Live, and Chelsea Lately will welcome her on March 21.
