Just as Miss California Carrie Prejean's overextended fifteen minutes appeared to be coming to a close, a dramatic new twist: Her mom is a lesbian, a woman claims.

Prejean became an overnight Christian celebrity after she denounced gay marriage because of her religious upbringing during the Miss USA contest and aligned herself with Maggie Gallagher's anti-gay marriage group the National Organization for Marriage (NOM).

Valerie Vetrano told ABCNews.com Wednesday evening that she had a lesbian relationship with Prejean's mom, Francine Coppola.

“I did date her,” she told the news outlet. “I'm not going to deny it, but I'm not going to say anything else.”

Reports about the affair were first published by Star magazine. Vetrano, an openly lesbian sales rep from Corona, California, said the relationship ended “a couple weeks before Carrie Prejean was in the Miss USA competition.”

Allegations about gay affairs surfaced during Coppola's 1996 divorce from the beauty queen's father, Wil Prejean. In documents obtained by gossip site TMZ.com, both parties reportedly made gay allegations against the other.

Despite a controversy concerning semi-nude photos, Prejean was allowed to keep her crown after Miss USA owner Donald Trump decided in her favor.
