Just in case you needed a reason to jump aboard the Nariana bandwagon, look no further than this adorable on-stage surprise from a recent The Wanted performance.
Nathan Sykes (Ariana Grande's new boyfriend) and his band-mates were serenading fans with their song "Heart Vacancy" when Ariana appeared -- or should we say, was carried -- on stage so that Nathan could sing to her. Looking visibly embarrassed, the "Right There" singer attempted to run behind the stage several times, but ultimately gave in.
Watch Nathan sing to Ariana in the video above.
