Iggy bows on Vibe

POWER UP THAT VIBE: The sole debut in Vibe-Raters this week is Island/IDJ's Iggy Azalea. The provocative Australian rapper and model and VMA Artist to Watch nominee is still seeing Rhythm Crossover action on first single "Work"; her new one, "Change Your Life" (from the EP of the same name, streeting 10/8) features a guest spot from T.I. The VEVO clip bows worldwide next week, and if the 20 million views earned by "Work" are any indication, it should garner a large number of eyeballs. Anyone who's seen her do her thing knows why the BBC named Iggy 2013's Hottie of the Summer. She'll warm up for Beyonce on Australian dates this fall, and, oh, remember before where we told you she's a model? Yeah, that hasn't been lost on Complex, Paper, Nylon, Interview and other tastemaker press. In other Vibe news, Ariana Grande jumps from #5-2, and The Weeknd moves #9-7.
