Justin Bieber unveils trailer for 'Believe' documentary

Nov. 17 (UPI) -- Justin Bieber's previous documentary, 2011's Never Say Never, became the third highest grossing documentary of all time, so it's no wonder that filmmakers were eager to capitalize on the Canadian singer's box-office pull once again.

The result is Believe, another feature-length documentary about Bieber's life in the public eye. The film also includes interviews with the 19-year-old's longtime mentor Usher and charismatic manager Scooter Braun.

The documentary will also address Bieber's scuffle with a paparazzo earlier this year. But it's unlikely to mention the singer's unlucky visit to South America, which included alleged rendezvous with prostitutes and a vandalism charge.

Believe hits theaters Christmas Day.
