Reese Witherspoon and Tyra Banks are lending their support to a charity auction raising funds for the American Cancer Society.

However, rather than just sign some movie memorabilia, Reese Witherspoon is designing a fairytale wedding gown.

We suggest Reese Witherspoon rather parts with a troublesome Chanel dress she wore at Golden Globes (the one that was worn by Kirsten Dunst a few years ago.)

The dresses will be sold via www.charityfolks.com, along with other lots including a signed Brokeback Mountain script and the jacket Samuel L Jackson wore in Shaft. (SOURCE: IMDB)
