Gibson and Schwarzenegger to bid farewell to Leno

Mel Gibson and Arnold Schwarzenegger will help Jay Leno wrap up his tenure as the host of America's 'The Tonight Show' by agreeing to be among the funnyman's final big-name guests.

The two Hollywood heavyweights will join Prince, Lyle Lovett and Billy Crystal among the celebrities who will visit Leno for his final week of shows, beginning on May 25.

It is not known if Gibson will talk about his divorce when he sits down to talk to Leno, but Schwarzenegger is sure to fire up the ratings - he announced that he would be running for office as California Governor on the show in 2003.

Comedian Conan O'Brien will take over from Leno as the host of the beloved show.
