"Far worse than that," responded the 24 star. "I lost a bet. Over the weekend, I was so sure New England was gonna win [the NFL playoff game] that I told a guy who used to be my friend that if new England lost, I would wear a dress on Letterman."

Letterman upped the ante.

"You ride the subway, I'll give you a thousand dollars," he joked. "You get on the subway like that... downtown."

"Riding the subway would be easier than what I'm going through right now," he said. "This I think may be the most humiliating moment of my life, and I've had a couple to choose from."
