Hollywood actor Russell Crowe has thrown his support behind Justin Bieber after the troubled pop star became embroiled in a graffiti dispute in Australia. The Baby hitmaker, who is currently on tour Down Under, hit headlines there this week (beg25Nov13) when he was caught spray-painting a wall in the grounds of the hotel where he was staying on the Gold Coast. The area's mayor, Tom Tate, was furious with the singer and publicly ordered him to clean up his mess. However, New Zealand actor Crowe, who is based in Australia, insists he likes seeing Bieber's graffiti artwork and backed him in a post on Twitter.com, writing, "I like Bieber's tagging. Tag on little brother. Tag the world." Bieber previously found himself in trouble with the law over his 'tagging' during his South American tour after he was accused of spraying an abandoned hotel building in Rio de Janeiro, Brazil.
