Big Sean will not be a "best mistake" for Ariana Grande anytime soon. The unconfirmed couple held hands during her concert on the Honda Stage at the iHeart Radio Theater in LA. They are both dressed in all black for the song that speaks of two lovers who break up and can't seem to move on. The duo acts out the song for the audience during Sean's verse, as Grande breaks her hand away from Sean and eases back in her chair to display a lost love. This concert was to promote Ariana Grande's sophomore album, My Everything, which debuted at No.1 on the Billboard chart.
