Letterman Lets His Guard Down - Esquire

Those who know him best speculate that he could, on any given Monday, show up for work, having quietly married girlfriend Regina Lasko over the weekend. It has yet to happen. It did happen once, long ago, back in Indiana, when he took himself a college bride, named Michelle Cook, for a term of seven years. "For what I put her through," he has said, "I should burn in hell for the rest of my life." Lasko, whose profile is kept so low as to be invisible, is said to be warm, devoted, bright and patient, now in her fifth year of involvement with Letterman. They met when she worked at Late Night, after which she became a production manager for Saturday Night Live, before quitting altogether last year.
