Ariana Grande Talks 'Problem' Single & Second Album, Due Out August/September

When Ariana Grande's first album, "Yours Truly," started at No. 1 on the Billboard 200 last September, the 20-year-old singer became just the 15th female solo artist to guide their first full-length to a No. 1 debut on the albums chart. Grande tells Billboard that she celebrated that accomplishment for approximately one hour after it happened, and then began thinking about her next album.

"I'm a workaholic, and a perfectionist," says Grande, who released "Problem," the first single from her as-yet-untitled second album, on Sunday night (Apr. 27) after performing the Iggy Azalea-assisted track for the first time at the Radio Disney Music Awards. "It was a very exciting thing for me to all of a sudden have this new mission, to make something as special as 'Yours Truly,' and to put my time and effort into something new and something I want to make just as good, if not better."

Grande believes that she hit that mark with her sophomore effort, due out in August or September: "I never thought I'd be able to say this, but I love this [album] five times as much as I love 'Yours Truly.' They're different, but I love this one so much more."
