Avril Lavigne offering to let fan dance with her on stage

Avril Lavigne is letting one lucky fan dance on stage with her at an upcoming concert to raise money for charity.

The Complicated hitmaker is auctioning off a gift package, which includes tickets to one of her gigs in either London or Paris, France, later this month (Sep11), a backstage meet-and-greet - and the chance for one lucky devotee to rock out with Lavigne during the show.

All the proceeds from the auction will go towards the singer's Avril Lavigne Foundation R.O.C.K.S. - Respect, Opportunity, Choices, Knowledge, and Strength - which supports children living with serious illnesses and disabilities.

Lavigne launched the foundation last year (10).
