The Baby hitmaker is lending his support to the Great Ormond Street Hospital Children's Charity by auctioning off a special meet-and-greet package for his 2011 concerts.
Devotees can also dress like Bieber - the singer is selling off T-shirts, jackets, jeans and pairs of sneakers from his own closet as part of the auction.
The sale kicked off on eBay.co.uk on Thursday and will continue until 12 December.
Bieber will embark on his first U.K. tour in March, with dates in cities including Birmingham, Liverpool, London and Manchester.
