Madonna surprised Parisiens with an impromptu performance as she paid tribute to the victims of the attacks in the French capital.

The 57-year-old pop star is in Paris for her Rebel Heart tour.

After her sell-out concert at the Bercy Arena on Wednesday, the singer tweeted to say she was heading over to the Place de la Republique which has been the focus of Paris rallies against terrorism.

Videos online feature the star singing with her 10-year-old son David, accompanied by guitarist Monte Pittman, who is currently on tour with the artist.

The crowd joined in with the impromptu show, but the multi award-winner appeared to have forgotten some of the lyrics to John Lennon classic Imagine.

She also sang smash hit Like A Prayer and Ghosttown, taken from her Rebel Heart album.
