Appearing on CBS' The Late Show on Thursday night, Oprah Winfrey ended her supposed "feud" with David Letterman, going so far as to gift him with an autographed photo of her and Uma Thurman. "I want you to know: It's really over, whatever you thought was happening," Winfrey told the late-night host. In case their first one-on-one in 16 years went sour, Letterman had Tony Danza waiting in the wings as a "stand-in host." Seriously. THIS JUST IN: The OprahMan lovefest drew Late Show's highest ratings since February 1994, luring 13.5 million folks hoping to see Dave get bitch-slapped..
