Justin Bieber and his tour director Jon M. Chu are searching for dancers online for the singer's "Believe" tour. "Justin also has such a huge online component, that's where he was discovered. You can upload your own video and audition," femalefirst.co.uk quoted Chu as saying. Both of them have already been auditioning dancers. Meanwhile, it has been revealed that the 18-year-old is preparing for his tour by studying the late Michael Jackson's moves.
