In an Associated Press story, David Letterman says the scandal surrounding his workplace relationships initially "knocked him down" and left him depressed, but that now he's putting the pieces of his life back together.

During a guest shot on Friday's "Live! With Regis and Kelly," the CBS late-night star said his behavior was stupid and reckless, and that it hurt his family and himself. But he sounded hopeful that life with his wife and young son can "even be better, in a different way" than before the explosive revelations that he had had sex with female "Late Show" co-workers.

Letterman made no reference to the $2 million shakedown attempt to expose his sex life that spurred him to reveal the affairs during an extraordinary monologue on his show last October.
