Oprah‘s announcement that she will be leaving her daytime television outpost in 2011 after more than two decades seems to have opened the door for her best friend, Gayle King. An insider tells Page Six that King, currently editor-at-large at O magazine, is in talks with CBS to get her own show after Oprah goes off the air. King was given a syndicated talk show, “The Gayle King Show,” in 2007, but it was canceled due to bad ratings. A rep for King did not respond to a request for comment.
