This Spring, the iconic Lindt Gold Bunny is celebrating its 60th birthday, and to make it a birthday to remember, Lindt is kicking off Easter one month early with a celebrity auction benefiting Autism Speaks. Between now and March 18th, porcelain versions of the Lindt Gold Bunny, autographed by celebrities in the entertainment, food, music and sports communities, will be up for auction from the Swiss chocolatier.

Katherine Heigl is one of 75 stars who have lent their signatures to the unique ornamental pieces. In honor of National Autism Awareness Month, 100 percent of the proceeds from the auction will benefit Autism Speaks.
