David Cameron has auctioned off Justin Bieber for £10,000, without the pop star's knowledge.

In a curious mix of cautious Conservatism and candy-floss coated Canadian crooning, the PM offerred exclusive backstage passes as part of a Tory fundraiser.

A wealthy donor won the bid but one person has yet to be told of the sale- Bieber himself.

Four lucky girls will get to meet the star

The Sun claim the singer wasn't told about the deal, which has prompted Labour MP Steve McCabe to slam the party over the "cynical" stunt.

The teenage pop sensation is playing London's O2 arena on March 7th and his record label donated the prize of "every girl’s dream" to "meet face to face with the gorgeous teen heart-throb."

But the meet and greet is probably the last thing on Bieber's mind, as he reportedly spent time over the weekend with his on/off girlfriend Selena Gomez.

Us Weekly claims the former Disney star was seen leaving her ex's Los Angeles home early on Saturday morning.

A source added: "It never ends. We'll see. It's such drama with them." Young love eh?
