Avril Lavigne autographs purse blue

Last night Avril Lavigne enjoyed dinner with her girlfriends (and rainbow colored hair) at BOA just before she's about to kick off a promotional tour in support of her new album, Goodbye Lullaby.

Avril, who's barely recognizable these days from the surly, spitting punk princess who would flip the finger at the cameras, has a lot to smile about. Not only is her first album in four years dropping next month, but her first single off the album, "What The Hell" has cracked the top ten.

Plus, there's her serious relationship with Brody Jenner that seems to be keeping her awfully happy!
