Letterman apologizes to wife on his show

NEW YORK: David Letterman, days after revealing on air that he'd been sexually involved with women from his television program, apologized to his wife on Monday's Late Show, saying she had been "horribly hurt by my behavior" and stating flat-out those affairs "are in the past".

The CBS late-night host, building on Thursday's startling confessional, vowed to repair his relationship with his wife, Regina Lasko, whom he married in March after a years-long courtship. "Let me tell you folks, I got my work cut out for me," he said ruefully.

As Letterman faced Monday's show, and the shows that will come after, it was clear that how he deals with his messy situation could prove to be a defining chapter in his long TV career. And, ironically, it could clinch his recent ratings victory in late-night TV.
