POP-DIVA IN TRAINING Ariana Grande's Yours Truly is pure pop bliss

Big Sean is moving on up: The rapper only got to whisper in the background on Ariana Grande’s “Problem,” but he gets a full verse in the singer’s latest single, “Best Mistake.”

Grande’s most recent songs, including “Problem” and the recently released diva-off “Bang Bang,” are uptempo and energetic, but “Best Mistake” is a slow jam reminiscent of 2013’s Yours Truly with its gentle yet frantic piano and Grande’s mellow vocals.

Big Sean and Grande also collaborated on “Right There,” a single from Yours Truly that made its way onto the Billboard Hot 100 chart, peaking at the 84th spot.
