Happy 27th Birthday, Avril Lavigne! Hot Pics of the Rocker (PHOTOS)

Bikini Bodies: Guess Who?!
Can you match the Celeb with their bikini?
She’s been rocking crowds and winning the affection of Sk8er Bois for nearly 10 years now — can you believe “Complicated” was released in 2002?! — and on this fine day, Avril Lavigne is officially 27 years old.

Avril, who was born on September 27, 1984, has been belting out hits left and right over the last nine years, everything from her debut single “Complicated” all the way to her recent infectious I’m-young-and-ready-to-have-fun anthem “What the Hell?” Avril, who has been dating Brody Jenner recently, will be spending her birthday at home in her new home of Los Angeles, saying on Twitter:

Home for a couple of days. Then off to Canada the whole month of October on my tour. First show is in Victoria on Saturday who is coming??!!

Ten years ago, “home” was Canada, as the pop-punk crooner was born in Ontario.
