If you’re jealous of Audrina Patridge’s amazing body, smile and hair, she’s basically telling us we should be, because she’s claiming it’s all natural….

“When we go out, people think my mom is my sister and my grandmother is my mom!” she tells In Touch. “They’re gorgeous!” Of course, the body she’s now so thankful for didn’t always feel like a gift from the fairy godmother of good genes.

“In high school, I was so self-conscious because I was so thin. Girls would say, ‘Oh, you’re too skinny.’” Once the former Hills star took up Pilates and started adding muscle to her naturally slight frame, her self-esteem soared, and she currently holds the title of most confident among her two sisters, married mom-of-two Casey, 24, and 15-year-old high school sophomore Sammy. “I don’t know how she does what she does,” Casey tells In Touch of her sister’s glam, skin-baring spreads in magazines like Maxim. “But I think she’s always been flawless.”

While there’s been a lot of plastic surgery talk when it comes to Audrina’s transformation from girl-next-door cutie to total sexpot, she tells In Touch she’s never “done anything,” but doesn’t judge people who have. “To each their own,” she says. “I do think people take it to such a point where they regret it, though,” she adds.
