Will David Letterman’s longtime rival, Jay Leno, appear on his final episode of The Late Show With David Letterman? Don’t hold your breath. Executive Producer Rob Burnett told CNNMoney in an interview posted on Tuesday that he was invited but expressed doubt that he would make an appearance. He made his comments amid much fan speculation of such a reunion, as well as recent questioning on the air by Howard Stern, who is not a fan of Leno. Burnett called the relationship between Leno and Letterman “fascinating.” The two met in the ’70s in Los Angeles when they were standup comedians. In 1982, Letterman began to host Late Night, which followed The Tonight Show, then hosted by Johnny Carson. Both he and Leno had guest hosted The Tonight Show when he was away.
