Ariana Grande stopped by Ellen earlier today to perform her new single "Problem." While the 20-year-old pop star was without song collaborator Iggy Azalea, Grande still put on a performance that accentuated the finer points of the record. Mainly, her incredible voice.
"Problem" was released on April 28 and is expected to top the charts in its first week. Ariana Grande's latest single will be included on her upcoming sophomore album, which is set to feature fellow pop phenom Justin Bieber.
