George Clooney and Brad Pitt Release Photos in Sexiest Man Prank  11/30/06

Fun-loving George Clooney and Brad Pitt have been revealing embarrassing photographs of each other in less-than-flattering clothing as part of a joke rivalry.

Clooney was recently named Sexiest Man Alive by US magazine People for the second time. Pitt is the only other person to also have won the honor twice.

After Pitt published photos of Clooney from the 1980s, complete with a mullet hairstyle, in two American newspapers, Clooney got his own back on TV show The Late Show With David Letterman - where he revealed a picture of Pitt wearing a beret during high school.

Clooney said, "He has won two and I've won two. He was a little upset this time."
