British comedian and actor Russell Brand called it quits on his 14-month marriage to “Teenage Dream” singer Katy Perry Friday, filing for divorce on the grounds of irreconcilable differences. Brand, 36, star of the movie “Get Him to the Greek”, and US pop star Perry, 27, met in 2008 and married on October, 2010 in a lavish wedding in India. The irreverent, former drug addict and the perky Christian-raised singer of international hits like “California Gurls” and “Firework” seemed an unlikely match, but they quickly became one of the most high-profile couples in the entertainment industry. In recent weeks however, celebrity media reported that their marriage was in trouble. They spent the Christmas holidays apart, with Brand being photographed in England, and Perry spotted in Hawaii — both without their wedding rings. Perry, who first tried a career as a gospel music singer, transformed herself from what music critics thought might be a one hit wonder with the single “I Kissed a Girl” in 2008 to become one of the world's biggest pop stars. __
