Gwen Stefani at Children’s Foundation Children’s Hospital

Gwen Stefani will auction off memorabilia from her 2007 Sweet Escape world tour to raise money for California charities, the Orangewood Children’s Foundation and the Children’s Hospital of Orange County (CHOC).

Gwen says: “When I saw how successful the last charity auction was (in 2007), and how supportive and excited the fans were to be a part of it, I thought it’d be great to do another one. “To be able to share these amazing costumes with my fans and raise more money for CHOC and the Orangewood Foundation at the same time is very exciting.”

The auction will hit eBay on March 8th.
