Matt Damon Sports a Porn Mustache on 'The Early Show' (VIDEO)

Does Matt Damon have something about lips?

Damon was on 'The Early Show' (weekdays, 7AM ET on CBS) plugging his upcoming film 'Green Zone' and chatting with Harry Smith about some upcoming projects. "What's with the mustache," Smith asked him. "I'm going into porn," Damon responded. "It's really the only place left. But I'm going into '80s porn." Actually, he was growing a mustache for his upcoming stint on the Coen Brothers' remake of 'True Grit.' Later, Smith asked him about the rumors that he was going to play Liberace's young lover with Michael Douglas as Liberace. "Yes," Damon responded. "And as Michael said the last time I saw him, 'get your Chapstick ready.'"
