Tinie Tempah has been revealed as the mystery bidder who spent $37,500 on the first pair of Nike limited edition Back To The Future shoes.
Only 1,500 pairs of the Nike Air Mag shoes will be available at auction on eBay.com, and Tempah snagged the first lot on Thursday night (08Sep11), according to TMZ.com.
The shoes are replicas of the ones Michael J. Fox wore as Marty McFly in Back To The Future II.
All proceeds from sales will benefit the Michael J. Fox Foundation, which helps fund research on Parkinson's Disease, which the actors suffers from.
