U2 - The Edge and Bono U2 in concert, O2 Arena, London, Britain - 30 Oct 2015 Film star Matt Damon was spotted dancing to U2 at their concert in London. The American actor, whose film 'The Martian' is currently doing well at the box office, was among a host of A-list celebrities at the rock band's gig at the O2 arena. Matt, who was dressed casually in a grey T-shirt and black Champions beanie, was standing near the front of the arena with actor Bradley Cooper and singer Noel Gallagher. Rock star Mick Jagger and artist Damien Hirst were also at the concert. Matt, who later removed his beanie and was seen wearing glasses, posed for photos with fans and danced along to U2's big rock anthems. Noel Gallagher, who performed on stage with the band earlier in the week, was also spotted high-fiving fans as they walked past him. The U2 concert was part of the band's Innocence and Experience Tour, which will see them play 20 cities in Europe and North America. Image Credit:

U2 have postponed their Saturday night concert in Paris in the light of the deadly attacks across the city on Friday night.

Instead, the band said in a statement that it is resolved to go ahead with the concert “at an appropriate time”.

U2 members say they watched in shock and disbelief at the unfolding events and were devastated by the loss of life at the concert held by Eagles of Death Metal, one of several sites in the city that was violently attacked.

“We hope and pray that all of our fans in Paris are safe,” members of U2 said.

HBO had planned to televise the band’s performance.
