Rosie O'donnell is hoping to persuade pal Madonna to direct an episode of hit plastic surgery drama Nip/tuck, after playing a recurring role on the show.

The actress and U.s. TV personality has played lottery winner Dawn Budge on a handful of episodes of Nip/Tuck, since making a naked debut in 2006 - and now she wants her pal to get on the set.

Show regular Kelly Carlson says, "Madonna's been approached because Rosie is on our show and they're very good friends. I've begged the producers to get her on the show."

"She has such a great mind for stuff like this that I think she'd be a great director for an episode. I would also love to have Madonna on as a character."
