Biggest accomplishment this year: Lining up the release of her debut studio album, The New Classic
It's been a big year for Iggy Azalea, who's gone from a YouTube star to appearing alongside the likes of T.I. and B.o.B at the BET Hip-Hop Awards and touring the country with Macklemore and Ryan Lewis. She was named the new face of Levi's jeans in the fall of 2012, and prior to that had signed on with Wilhelmina Models International and been featured in XXL Magazine's Top 10 Freshman issue. Her debut studio album, called "The New Classic" is slated to release this summer.
