Miley Cyrus has organized a celebrity auction on eBay to benefit Haiti relief. Along with donating the blue Herve Leger minidress she wore to the Grammys, Cyrus also collected items from pal Demi Lovato and Hugh Jackman. "Everyone has been so generous," the pop star told People.com. "My mom and I started calling and texting all of our friends to see if they'd like to be a part of the auction." The auction begins today and ends on February 18—all proceeds go to the American Red Cross.
