Sutherland wears dress on 'Letterman'

Kiefer Sutherland donned a dress for his appearance on last night's instalment of The Late Show With David Letterman.

The 24 star joined Letterman on stage wearing army boots and a green patterned dress with a long-sleeved white shirt underneath.

He explained that he was wearing the outfit because he lost a sporting bet with a friend.

"I lost a bet over the weekend, I was so sure New England was going to win that I told a guy who used to be my friend that if they lost I would wear a dress on Letterman," he said.

"The guy I made the bet with, this is the end of our friendship, the end of the debt that I had for the bet. This is it!"

Letterman joked that he would give Sutherland $1,000 to ride the subway in his dress, prompting the actor to say: "Riding the subway would be easier than what I am going through right now. This is the most humiliating moment of my life!"

The Late Show airs on CBS.
