Actress Mary Kate Olsen is so happy with her new-found curves, that she is giving her clothes away. The ones that no longer fit her, that is.

The socialite has been fighting with an eating disorder in 2004. The battle lasted almost a year, and, after the actress gained approx. 15 pounds (6.8 kilograms), she declared the war won.

Therefore, she decided to get rid of the skinny wardrobe, by donating it to West Hollywood, California thrift store "Out of the Closet", a charity shop that benefits AIDS research.

The shop is a popular place for celebs who want to donate clothes, Winona Ryder and Elizabeth Taylor being among the ones who have regularly given away items.

Mary Kate Olsen's former boy-friend, Stavros Niarchos, has just announced he is to marry Paris Hilton.

The two got engaged last week. Hopefully, Mary Kate will not be very much annoyed by the news for that to endanger her so hard gained curvy silhouette. Paris Hilton had dumped her other Greek boy-friend, saying she is too young to get married. But old enough to be engaged?
