Celebrity Gossip

How do you feel about those gossip magazines? You cannot understand how someone can be permanently interested in other people's private life? Same here.
However, yesterday I photographed some celebrities at the museum of natural history. It was the world premiere of "Night at the Museum" and also the reason why my friends and I couldn't see the space show we wanted to see. Instead we photographed Ben Stiller and his father Jerry on the red carpet.
There is one star in this movie who didn't show up at the premiere: Robin Williams. Now the mysterious part: While we were staying around there waiting for the big limousines, I noticed (and I think I was the only person who noticed him) a homeless man. I found him interesting looking with a radio around his neck. Later when I looked at these pictures again, I was quite excited to find out that he actually looks very similar to Mr. Williams. I searched the internet for a picture of Robin Williams' profile and found one. What did Robin Williams do last night? Was it him hanging around incognito?
