The "Fancy" rapper, 24, dished to the mag for the April issue, explaining, "Four months ago, I got bigger boobs! I'd thought about it my entire life."
Insiders tell Us Weekly that Azalea underwent the procedure on Nov. 19 in Los Angeles, turning to Beverly Hills-based plastic surgeon Dr. Ashkan Ghavami. The highly rated medical professional specializes in Flash Recovery, a treatment that allows patients to be back on their feet in just days.
The quick recovery period was essential for Azalea, as she was scheduled to perform at the 2014 American Music Awards just days later. The Grammy-nominated performer took the stage at L.A.'s Nokia Theatre on Sunday, Nov. 23, four days after she went under the knife.
A source tells Us, however, that the surgery did require the Aussie to do less strenuous dance moves. It also impacted her wardrobe for the evening, as she was still sporting bruises from the procedure. A second source tells Us there was "no way" that the artist could wear a cleavage-baring number and instead wore bandages under an outfit that covered her entire chest.
Azalea performed "Fancy" and "Beg for It" with Charli XCX and turned up the heat with Jennifer Lopez for a performance of "Booty." She also took home the honor of Favorite Rap/Hip-Hop Album for The New Classic and won Favorite Rap/Hip-Hop Artist.
Nick Young's girlfriend was hardly secretive about the work that she had done, volunteering the information to Vogue and even posing for a photo with Dr. Ghavami the month of the surgery. The doctor, who has also snapped shots with Tori Spelling and Blac Chyna, posted a photo via Instagram with Azalea five days before her surgery.
"Greek yogurt kinda morning with @thenewclassic," he captioned the image of himself and the rapper chowing down on yogurt. "Such a sweetheart. #drghavami #iggyazalea."
