The buyer will be able to go backstage and meet the Baby hitmaker at his gig at London's O2 Arena on 7 March.

A wealthy financier is believed to have paid more than £10,000 for the prize, which was gifted to four teenage girls.

Access to the 18-year-old star, described as "every girl's dream" in the catalogue advertising the auction, was reportedly donated by Universal Music UK, his record label in Britain.

Although the singer was unaware of the auction prize, a a record label spokeswoman said that Bieber "wouldn't expect to be informed" about who got special passes for backstage meetings.
