Justin Bieber's Next Big Adventure: Pee-wee Herman's Movie?

Pee-wee makes a plea from Comic-Con for singer to cameo in his Judd Apatow-produced film.

SAN DIEGO — Beliebers are in luck, because Justin Bieber might be heading to the big screen once again soon, if Pee-wee Herman has his way.

Turns out Herman, who has been working on a new film alongside producer Judd Apatow, has recently written the VMA nominee in as one of the celebrity cameos. The only problem? Bieber doesn't know yet.

"I can't really tell [what the cameo is], but he makes an appearance toward the end of the film," Herman (actor Paul Reubens, but we definitely interviewed Pee-wee) told MTV News at San Diego Comic-Con. "He doesn't know about it yet, so if you're watching this, Justin!"

That's not the only grade-A cameo Herman has written into the script. He has his eyes on lots of stars — and the White House.

"There's a party scene in the film that I think will have a lot of the stars. We just wrote President Obama into them. We have an offer out to him," Herman unveiled. Will any other government officials be given a role in the movie? "Sarah Palin wasn't asked. I have to draw the line somewhere, and unfortunately that's where it was drawn. I'm sorry, Sarah, I'm sorry," he whispered.

The script for the currently unnamed comedy is being looked at by Universal Studios at the moment, and Herman said he hoped filming could begin within the next couple of months. It only helps that he has Apatow in his court and that the director/producer has words of wisdom to pass on to Herman to make the best comedy he can.

"He's given us the same advice over and over again, which is 'emotional arc,' " Herman explained. "He wants the character to go through an emotional arc and to come out on the other end arced. So that's what we're doing. We're adding an emotional arc. Emotional growth, so there's a change in Pee-wee Herman during this film. Pee-wee makes a change."
