Good girl Audrina Patridge has at least one thing in common with estranged Hills costar Heidi Pratt: plastic surgery.
Although the 25-year-old has publicly denied it, a pal confirms to Us Weekly that Patridge went under the knife -- and it was just the confidence boost that she needed.
The aspiring actress "feels she has to be perfect to continue her career in TV and film," the pal continues. (After The Hills wraps later this year, Patridge hopes to launch her own reality TV show with producer Mark Burnett).
Now, with noticeably larger breasts, "She think she has a banging body," a friend says. Adds another: "she's confident in her looks. I don't think she'll get more surgery."
Her nemesis Spencer Pratt famously dissed Patridge's reported procedures, slamming her "nasty Tijuana plastic surgery" on Twitter recently.
Pratt's vicious attacks get under her skin, another friend says: "You can't mention his name without Audrina spewing 'Did you hear what he did this week?' She hates him."
To find out how Audrina has become "wiser to men" after years of drama, and get new details on her romance with singer Ryan Cabrera, her discovery by a casting producer, and the unwelcome return of her ex Justin "Bobby" Brescia, pick up the new Us Weekly, on newsstands now.
