"Supernanny" hanging up her cape?

Jo Frost -- who started out starring on the U.K. version of "Supernanny" in 2004 -- is making noises that she's prepared to exit the show.

But first, ABC -- which debuted the American version in 2005 -- has given "Supernanny" a 13-episode order for the upcoming 2010-11 TV season. Frost is shooting those segs.

After that, Frost said she's ready to call it quits.

"It feels like the right time for me to end my reign as the Supernanny," Frost said. "I've lived out of a suitcase for the past five years, visiting 47 states for the show. It's time to settle down in one place for the time being."
