Fred Durst Working With Avril Lavigne?

Limp Bizkit frontman Fred Durst is saying he is working with Avril Lavigne on her new album, according to the New York Post. “They are spending a lot of time together right now,” a Durst source said. “He even jumped on stage with her last week during her Lowell [Mass.] show.” Lavigne’s rep denied the claim Durst was working with the Canadian teen.
