Lavigne Not On Lil Wayne's Rebirth

Avril Lavigne isn't on Lil Wayne's Rebirth, according to a representative for the Napanee, Ont. pop tart.

Rollingstone.com referred to a Lavigne cameo in an article about a leaked version of the overdue album back in March, and the word spread from there. But the 24-year-old singer/songwriter's label says she didn't contribute to the rapper's "rock" crossover record.

Fall Out Boy, Lenny Kravitz and Aubrey "Drake" Graham haven't denied their involvement with Rebirth, which is now slated to be released on July 21. But Drake denies he has something going on with Rihanna.

Aside from rumours circulating about Lavigne's marriage with Sum 41's Deryck Whibley being in trouble, there's been little news from Lavigne of late since she stopped touring in support of 2007's The Best Damn Thing.

It's not known when the follow-up to that record will be released, but Lavigne will represent Canada at the 2010 World Expo in Shanghai, China and recently released a fragrance.
