The R.I.P. hitmaker took to the stage at Radio 1's Big Weekend event in Norwich, England on Sunday (24May15) and during her set she performed I Will Never Let You Down, a track she worked on with Scottish star Harris prior to their split last year (14).

Before launching into the song, she told the audience, "You know when there is a song and no matter what happens the music still stands for itself."

She appeared to grow emotional during the track, and at the end of the song she seemed to wipe away tears before adding, "I get so emotional."

Ora appeared on the stage just hours before Harris' new girlfriend Swift played a set at the same event.

Other performers at the festival included Foo Fighters, who closed the event on Sunday.
