Avril Lavigne has recruited her celebrity friends Lady Gaga, Katy Perry and Taylor Momsen to donate items to a charity auction.
The Sk8er Boi star has been organising the Rockstar Auction to raise funds for her Avril Lavigne Foundation R.O.C.K.S. - Respect, Opportunity, Choices, Knowledge, and Strength - which supports children living with serious illnesses and disabilities, and the online sale launched on Thursday (30Aug12).
Lavigne's new fiance Chad Kroeger's band Nickelback are also among the generous participants, as well as her ex-husband Deryck Whibley and his group Sum 41 and rockers Train.
