David Letterman & Harry Are Happy Strollers

David Letterman and his 6-year-old son Harry were all smiles as they strolled hand-in-hand in New York City on Thursday (December 3).

The day before, David's estranged wife Regina Lasko, was pictured strolling with their son in New York City.

David apologized to Regina on the air in October 2009 after it was revealed he had affairs with women on his staff - affairs which landed him in the middle of an extortion scandal.

She has been horribly hurt by my behavior, and when something happens like that, if you hurt a person and it's your responsibility, you try to fix it," Letterman said during his opening monologue. "At that point, there's only two things that can happen: Either you're going to make some progress and get it fixed, or you're going to fall short and perhaps not get it fixed, so let me tell you folks, I got my work cut out for me."
