The directors of the Miss California USA pageant are looking into whether title holder Carrie Prejean violated her contract by working with a national group opposed to gay marriage and by posing semi-clad when she was a teenage model.

Pageant spokesman Roger Neal said Tuesday it appears the 21-year-old Prejean has run afoul of several sections of the 12-page contract that prospective contestants were required to sign before competing in the state contest.

The contract contains a clause asking participants whether they have conducted themselves "in accordance with the highest ethical and moral standards" and if they've ever been photographed nude or partially nude.

Prejean spokeswoman Melany Ethridge said she couldn't comment on the contract because she's unfamiliar with its contents.

Prejean said Tuesday that a Web site had posted racy photos of her in an attempt to belittle her Christianity.

The current Miss California said photos taken of her as a teenager had been released "surreptitiously to a tabloid Web site that openly mocks me for my Christian faith."

In a statement, Prejean also says the attacks on her and others who "speak in defense of traditional marriage" are intolerant and offensive.

A photo of Prejean wearing only pink panties with her back turned to the camera appeared Monday on the gossip blog theDirty.com.
