One thing’s for sure: Big Sean and girlfriend Ariana Grande make sweet music together. While the cute couple has been harmonizing outside of the studio lately, the Finally Famous rapper dished to MTV News about the couple’s insane musical chemistry inside the studio. Sean said “I was probably one of the first people to ever tweet about her music. We’ve been friends for years before anything else.” Big Sean also hinted at another possible partnership with the 21-year-old “Problem” singer on his upcoming project, Hall of Fame, saying “You’ve got to wait and see. I can’t spill the beans.”
