Hollywood stars Rachel Bilson, Kristen Bell and Busy Philipps are auctioning off the ultimate girly days out to raise cash for an educational charity.

Fans can bid on the chance to go shopping or enjoy manicures with their favourite A-listers as part of the LA School Life 2012 Auction in aid of the non-profit organisation Communities In Schools.

Actress pals Bilson and Bell have teamed up to offer a fun-filled shopping spree in Beverly Hills, while Cougar Town star Philipps is auctioning an hour-long cake baking session.

Ali Larter is offering a trip to her favourite day spa in West Hollywood for a manicure and pedicure, and a double date with actress Amy Smart and her husband Carter Oosterhouse is also going under the hammer.

A meet-and-greet session with Elijah Wood on the set of his show Wilfred and a private singing lesson with former American Idol contestant Paul MCDonald are also up for grabs on the Charity Buzz website.

You can bid at the auction site charitybuzz.com until Wednesday, May 16th!
