Sneak a Peek at 'Nip/Tuck's' Celebrity Surprises!

Julian McMahon, Dylan Walsh and the rest of the "Nip/Tuck" gang are in for an all-star invasion in the new season.

And "Extra's" confirmed the show's creator, Ryan Murphy, is currently writing a part for superstar Madonna.

As for rumors Nicole Kidman will also guest-star on the hit F/X show, Murphy told us it's a possibility.

"She wants to do something where she wears a lot of prosthetics. She thinks that's fun," Murphy dished.

But will Julian's "Premonition" co-star Sandra Bullock show up at the offices of McNamara and Troy?

We were with the stars at the Museum of Television and Radio's William S. Paley Television Fest, where we got the full celebrity dish!

An all-new season of "Nip/Tuck" debuts in September.
