Selena Gomez performed a surprise collaboration with a Christian band on Thursday (February 25).

The singer played with Young & Free at the Belasco Theatre in Los Angeles.

The group are part of Australia's Hillsong Church, which is aimed towards younger people.

Gomez joined the band on stage to perform her 2015 song 'Nobody'.

The US star told a fan on Twitter last year that God inspired her to write the track.

The tune features on Gomez's latest record 'Revival'.
