Iggy Azalea is getting real about her body in a new interview with Vogue.

When the high-fashion magazine asks if there's something the 24-year-old Australian rapper would change about her famous physique, she surprisingly drops this bombshell.

"I did change something: Four months ago, I got bigger boobs! I'd thought about it my entire life," Iggy reveals, explaining to Vogue that she was sick of having to sew padding into her stage costumes and that she wanted to wear lingerie without the wiring.

Though it happened a while ago, Iggy initially refused to talk about her plastic surgery publicly because she didn't want any of her young female fans to feel bad about their own bodies. "But then, I decided I wasn't into secret-keeping," she muses.

Still, Iggy laments that it's hard to shop for clothes, even with her new shape -- specifically when it comes to her famous derriere.

"It's about proportion," she says. "I have to have everything tailored because I have such a small waist. I’m a 2 or a 0 on the top, and a 6 on the bottom."

And though she now clearly embraces her curves -- as evidenced by her "Booty" collaboration with Jennifer Lopez -- she admits that this wasn't always the case.

"When I first got to the States, people told me I should think about modeling," she recalls. "So I went to a few agencies, but once they measured my body they didn't like me anymore."

Being told to lose weight and to get a nose job took the predictable toll on her self-esteem. "I was looking in the mirror a little differently," she shares.

Iggy is similarly guarded when she stars in Vogue's "73 Questions" series -- if you're expecting the feistiness of the girl who gets into Twitter feuds with everyone from Snoop Dogg to Papa John's Pizza , think again. She's downright demure in the single shot video, in which she gives a peek into her amazing studio in Los Angeles.

"I think it's a total mess but it's awesome," she says about the pitfalls of being famous. "[Dealing with press is] like talking to a serial killer that's extremely charismatic."
