David Letterman, 61, revealed to his Late Show audience on Monday night that he married his longtime girlfriend Regina Lasko, 48, on March 19 in Choteau, Montana. "I had avoided getting married pretty good for, like, 23 years," the famous bachelor said during the show. "I secretly felt that men who were married admired me, like I was the last of the real gunslingers." The couple have a son, Harry, 5, who attended the ceremony. (Photo: WENN)
