At Leno's Last Show, Conan Will Be a Guest

Jay Leno couldn't be happier that Conan O'Brien will be taking over The Tonight Show, reports N.Y. Daily News. He seemed to prove his statement true by announcing O'Brien to be his final guest on May 29.

Leno's final week is filled with a star-studded cast. There will be appearances from Arnold Schwarzenegger, Mel Gibson, Wanda Sykes and Billy Crystal, according to N.Y. Daily News. Billy Crystal will be completing the circle of time, since he was Leno's first guest after he took over for Johnny Carson.

Die-hard Leno fans won't have to wait too long however. His new prime-time show on NBC will begin in September, reports the New York Times.

According to Hollywood Insider, Leno promised the transition to O'Brien will be a smooth one.

O'Brien, former Late Night host, will be taking over the reigns for Leno on June 1.
