A tiara and gold cuffs apparently aren't in the future of Katharine McPhee, who says she isn't interested in portraying superhero "Wonder Woman" on film.

Last season's American Idol runner-up told Entertainment Weekly that playing the Justice League heroine would be a "huge mistake," Burbank, Calif.-based TMZ.com said Monday. She added that prospects for a Wonder Woman movie weren't very good and that production is in the very early stages of development.

McPhee also said suggestions that she skipped the first three weeks of the Idol tour are "totally false," and said her new record will surprise her fans, TMZ.com said. "People in the industry are hearing about what I'm doing, and they're really surprised, and I like that," she was quoted as saying.

And, she said when she poses for the cover of Shape magazine, she won't be some "slutty female," TMZ.com said.
