Matt Damon fears his thrill of getting a star on the Hollywood Walk of Fame will be marred when he sees someone urinating on it. The actor was thrilled when he was invited to unveil the honour and couldn't believe the day had actually arrived when he attended the ceremony on Hollywood Boulevard on Wednesday (25Jul07). He said, "I can't believe I'm standing on a star with my name on it. I'm going to show my kids that. "(Pal) Ben (Affleck) and I lived in a really crappy apartment about five blocks away from here and we used to walk up and down here. "This'll probably sink in when I walk down the street in about six months and see someone peeing on my star."
