Iggy Azalea wows at the 2014 Billboard Music Awards

LAS VEGAS, May 19 (UPI) -- Iggy Azalea wowed fans Sunday evening at the 2014 Billboard Music Awards.

The 23-year-old singer arrived on the red carpet in a sexy burgundy gown with lace-paneled cutouts and sleeves. Beau Nick Young accompanied her to the event, and the pair were all smiles as they joked around and posed for photographs.

Azalea later donned a cheeky cheerleader-inspired outfit for her performance of Fancy during the ceremony. She and Charli XCX delivered a sassy rendition of the hit song that had the audience singing and dancing along.

The star briefly exited after Fancy to make way for Ariana Grande. The 20-year-old singer wore a black and white mod-inspired dress and go-go boots for her performance of Problem. Azalea returned on stage for her rap verse in the song.

Fancy and Problem are currently numbers three and four, respectively, on the Billboard Hot 100 chart. Azalea is the third female singer to have her first Hot 100 hits reach the top five at the same time.
