Former Miss California Carrie Prejean refused to take a gay caller's question Wednesday night on Larry King Live, then threatened to walk out on the show.

The pair wrangled about a lawsuit settlement before King put the caller on the line.

King asked Prejean, who was only interested in peddling her just released book Still Standing, why she settled a lawsuit against the Miss California USA Pageant.

“Why settle since you had a fight to carry on?” King asked about the million-dollar lawsuit.

Prejean objected to the question, calling it and King “inappropriate.”

King moved on to taking a caller's question: “Hi, I'm calling from Detroit. I'm a gay man and I love pageants. I'm sure that you, Carrie, have got, you know, great gay friends that helped you possibly win. What would you give them as advice if they wanted to get married?”

An awkward silence followed as Prejean began speaking to someone off camera and removed her microphone. “Did you hear the question, Carrie?” King asked, followed by, “Who are you talking to?”

Finally, she answered: “Yeah, I think you that you are being extremely inappropriate right now. And I'm about to leave your show.”

Prejean's lawsuit against pageant officials claimed religious discrimination and libel. It has been widely speculated that she settled the suit after it emerged that she had filmed a secret sex tape when she was a minor. The 22-year-old has admitted to filming herself, telling Fox News: “It was me by myself. There was no one else with me. I was not having sex.”

Prejean attained celebrity status among conservative Christians after she denounced gay marriage because of her religious upbringing during the Miss USA contest in April. She said she lost the contest because of her answer, giving fodder to the conservative argument that supporters of gay marriage punish Christian opponents. A June release by the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, said Prejean's “values are in the right place.”

In September, speaking at the Value Voters Summit, she told a conservative audience that she was chosen by God to oppose gay marriage. Reflecting on the controversy, Prejean said, “I'm so proud of the answer that I gave. God chose me for that moment.”

Prejean was scheduled to speak at the Defenders of the Family, a fundraiser for the anti-gay group New Jersey Family Policy Council, on November 6, but was mysteriously removed from the event just one day prior.
