Ousted Miss California USA Carrie Prehean has something to get off her chest: She isn't a bad Christian because she got implants.

"No, I don't think there's anything wrong with getting breast implants as a Christian," Prejean, 22, says in a new interview with Christianity Today. "I think it's a personal decision. I don't see anywhere in the Bible where it says you shouldn't get breast implants."

She also weighs in on her recent sex tape scandal.

"There is a video out there of me. I was really young and immature. It was the worst mistake of my life," she says. "It was a really stupid, stupid decision that I made. But I take full responsibility for it. Did I think I would ever be a celebrity or that my boyfriend at the time, who I sent it to, would ever blackmail me? No. I think we all make mistakes and we all do things when we're young that sometimes backfire later in life. I give advice to younger girls in my book because I've learned a lot since I was 16 or 17 years old."

Despite also posing in some revealing photos when she was younger, she says she doesn't think parents will worry that she's not a good role model for their children.

"No one's perfect," she says. "You're not perfect, I'm not perfect. Everyone's made mistakes. So if people want to judge me and say that I'm not a good person because of something I did when I was young, that's their problem. But what really matters is who I am now."

Adds Prejean, "We as Christians need to stick together and realize that the Enemy is powerful, and that there are so many people out there who will try and destroy good people. It's a crazy world, that's all I can say. All Christians fall short, and hopefully mothers can hear my story and check their daughters' cell phones and Facebook pages. Young people are doing it every single day."
