NEW YORK - David Letterman had better start thinking up a top 10 list of baby names — he's about to become a father.
While taping the "Late Show" episode that's scheduled to air Friday night, Letterman told the audience Thursday that his girlfriend, Regina Lasko, is about six months' pregnant.
"I have an announcement to make and I'll be honest with you, I'm a little bit nervous. I have some trepidations about this. I feel a little silly because it's one of those things where I thought never in my life this would happen," the talk show host said.
"And here I am, 56, and by all rights it shouldn't be happening. But, there's nothing we can do about it now. And I'm terribly excited about this. I'm scared silly about this. I'm going to be a father."
