In celebration of her birthday this year, musician Avril Lavigne has started a promotion to raise funds for The Avril Lavigne Foundation, which helps support kids with serious illnesses or disabilities.

To aid the foundation, as part of their Rockstar Room, Ms. Grey has donated an exclusive autographed Gibson guitar, which you can now bid on via eBay!

Other musicians involved in the Rockstar Room include Sum 41, Simple Plan, Taylor Momsen, Neon Trees, and Travis Barker.
