After new single, the singer appears ready to compete with Taylor, Katy and Gaga
Ariana Grande knows how to make an entrance. After the 20-year-old R&B/pop star unveiled her new single, "Problem," with a performance at the Disney Music Awards on April 27, the song sprinted to a No. 3 debut on the Billboard Hot 100 dated May 17, thanks in part to one of the biggest sales starts ever. The Iggy Azalea-featuring cut, which hit digital retailers on April 28, sold 438,000 downloads in the week ending May 4, according to Nielsen SoundScan.
