David Letterman Apologizes to his Wife During Show Taping

ET has learned that on the heels of his revelation that he engaged in sexual relationships with his female staffers, David Letterman apologized to his wife Regina Lasko during a Monday taping of the "Late Show." Read on for details…

Letterman, 62, apologized for the attention and inquiries his family and staff members have received since his announcement.

"I’m terribly sorry that I put the staff in that position. Inadvertently, I just wasn’t thinking ahead. And, moreover, the staff here has been wonderfully supportive to me, not just through this furor, but through all the years that we’ve been on television and especially all the years here at CBS, so, again, my thanks to the staff for, once again, putting up with something stupid I’ve gotten myself involved in.
