The star fought back tears as she performed her iconic song at the Billboard Music Awards in Las Vegas.
The singer gave a surprise performance at Place de la Republique in tribute of the Paris victims.
Madonna gave an impromptu performance in Paris on Wednesday night in honour of the victims of the November 13th attacks.
The singer stopped by the Place de la Republique memorial site following a sold-out performance at AccorHotels Arena in the French capital.
Joined by her 10-year-old son David and a guitarist, she asked fans on Twitter to meet her there.
Madonna performed John Lennon's 'Imagine' as well as her own songs 'Ghosttown' and 'Like A Prayer' to a small crowd who joined in with her.
“Everyone knows why we’re here,” the singer said. “We just want to sing a few songs about peace, just to spread love and joy and to pay our honour and respect to the people who died almost four weeks ago. And to spread light, we all need it.”
We love when a star uses their fame to do good and we think this was a beautiful touching tribute from Madonna.
