After 33 years as a clean-shaven late-night host, Letterman retired last summer and was replaced by Stephen Colbert. In a recent interview with NBC News' Tom Brokaw, he admits that he rarely thinks about his past life on TV. "It’s interesting, I thought for sure I would. And then, the first day of Stephen’s show, when he went on the air, an energy left me and I felt like, ‘You know, that’s not my problem anymore,''' he explained. "I’ve kind of felt that way ever since. I devoted so much time to the damage of other aspects of my life. The concentrated, fixated, focusing on that. …It’s good now to not have that."
He also thinks there should be more women in late night. "I’m happy for the guys -- men and women -- there should be more women," Letterman touts. "And I don’t know why they didn’t give my show to a woman. That would have been fine."
That being said, Letterman seems pleased with how the Late Show With Stephen Colbert is going. "You know, I’m happy for their success," he continues. "And they’re doing things I couldn’t do. So that’s great."
Letterman's full interview airs on June 12 at 10p/9c on NBC's On Assignment.
Since his retirement, Letterman has adopted a whole new look. Ditching his suits and his razor, the comedian looks nearly unrecognizable with his big beard and casual clothing. Here's a look at his transformation:
