The shock jock also delivered a sincere apology to Letterman. Years ago when they were both starting out in the biz, Dave used to call Howard regularly at home -- and he loved it. "But I betrayed you because I would go on the air and talk about what you spoke to me about," shared Stern. "And I know you were offended and you stopped calling me... I really want to apologize to you for doing that. And if you should call me again, I would not reveal what you said." Marcel Thomas/FilmMagic.com - February 3, 2011
