Washington, November 11 Former Miss California USA Carrie Prejean has admitted that a leaked steamy tape she shot while in her teens was "the biggest mistake" of her life.

The model revealed she was 17 when she made the raunchy video for an ex-boyfriend who later "betrayed" her and sold it.

"They can call it whatever they want to call it, but it was the biggest mistake of my life," Fox News quoted her as saying.

"I was all by myself and I was sending a boyfriend at the time who I loved and cared about a video of me ... I was not having sex with anybody and you call it whatever you want," she added.

The 22-year-old said she regrets making the tape, calling it bad judgment at the time.

She said: "I was a teenager at the time and never did I think it would ever come out. But it was bad judgment and it's embarrassing and it's humiliating to be talking about this now on national TV if you can imagine."

Prejean was stripped off her title after being caught up in a controversy involving her open opposition to gay marriage and a nude photo shoot.

She slapped the state organization with a lawsuit alleging she lost her crown over her religious beliefs. The pageant accused her of missing events and filed a countersuit.

Both the parties settled the legal spat after reaching a confidential agreement.

Prejean, who had been seeking more than a million dollars in damages, withdrew her demands after the lawyer for the pageant showed her a sex tape, featuring her as the protagonist, according to reports. (ANI)
