Avril Lavigne ‘Goodbye Lullabye’ party
Avril Lavigne partied it up last night in New York City for the release of her fourth studio album, Goodbye Lullaby. Wondering "What The Hell" Kim Kardashian was doing at the Canadian songbird's shindig? Remember on the reality TV family tree the "Jam" singer is step sister's with the InRock cover girl's current beau, Brody (and perhaps Kim's picking up a few more tips about the music biz as well). Check out the punky pop princess rock green and pink hair for her celebratory soiree.
