Kate Hudson played the supportive fiancee as Muse performed an intimate, sold-out gig in London.
The Almost Famous actress, who is engaged to frontman Matt Bellamy, cheered on her man and took photos at the War Child Brit Awards concert at London's O2 Shepherds Bush Empire.
She also faithfully sang along to the songs throughout the night, which included Black Holes and Revelations and the official 2012 Olympics anthem, Survival.
Matt sent his epic performance crashing to a crescendo, smashing his guitar into the drum kit and jumping on top of his piano.
Harry Styles turned up late to the concert, while Rita Ora, Jamie Hince - minus wife Kate Moss - and Luke Evans were among the celebrity guests at the one-off gig by the Brit-nominated group, which was hosted by O2 and War Child.
Some loyal fans had camped overnight to get a spot in the front row for Muse's smallest London show in 10 years, which saw them taking a break from their US stadium tour to play at the gig, supported by The Vaccines.
