David Letterman is opening up about his sex-and-extortion scandal for the first time—and he's doing it with none other than Oprah Winfrey, with whom he had a long-running and well-known feud. He admits he has "no one to blame but myself" for the affair with a colleague blowing up in 2009, Today reports. "Now, I feel better about myself, my relationship with my wife is never better, and it’s just because I want to be the person I always thought I was and probably was pretending I was," he says in an interview airing on the upcoming episode of Oprah's Next Chapter.
The interview, airing Sunday at 9pm on Oprah's network, also addresses Letterman's supposed rivalry with Jay Leno. It's just not true, Letterman says, adding that he and Leno "were always friends" before Dave was passed over so Jay could replace Johnny Carson at the Tonight Show. "And I will say—and I’m happy to say—that I think he is the funniest guy I’ve ever known," Letterman adds. But one dig slips through: "Therefore, the fact that he is also maybe the most insecure person I have ever known—I could never reconcile that." (Read more David Letterman stories.)
