Keira Knightley cheered on James Righton as his band kicked off their new tour.
The 29-year-old actress was spotted supporting her husband's group The Klaxons during their gig at the Hare and Hounds pub in Birmingham, England on Monday night (31.03.14).
A source told E! News: "It was the first time the band had played at the Hare and Hounds and Keira stayed for the night and was dancing the entire time, which I'm pretty sure is the sign of someone having a good time.
"I've heard from the small number of people who did manage to meet her on the night that she thoroughly lovely, sweet, polite and very unassuming."
The 'Anna Karenina' star managed to avoid being recognised by most of the band's fans.
The insider said: "She had arrived with the touring party and spent much of the afternoon and evening in the dressing room with the band until they went on stage.
"She then watched from the back of the venue with friends and family of the band and by all accounts remained unnoticed by the audience."
The 'Jack Ryan: Shadow Recruit' beauty and James, 30, got engaged in May 2012, after meeting through mutual pal Alexa Chung, and tied the knot in the south of France last July.
