Justin Bieber really loves his hometown of Stratford, Ontario. Fresh off a donation to the local food bank in the city, which he and his mom often relied upon in his youth, the Biebs has offered up autographed items that will be auctioned on eBay to raise funds for the local skate and BMX park.

The Biebs etched his John Hancock on the items while in Canada over Christmas, and now they will be used to earn cash to upgrade the park. The items will officially go on sale on Friday, Jan. 20 -- but there is a twist to the story, according to The Hollywood Reporter.

The autographed items became part of the fundraising drive somewhat inadvertently. Here's what happened: The Biebs' grandmother purchased a new car at a Hyundai dealership in Stratford. What, no Benz for Grams? She's going practical and economy with her ride? Nevertheless, the owner of the dealership asked Grams Bieber if her famous grandson could autograph a brand new set of wheels that would be auctioned off for charity and that evolved into Bieber agreeing to support the car dealership's other charitable efforts to upgrade the park, which has been in use since 2000.

As for that signed car? The Biebs inked his signature and music notes on the dash on Dec. 23. That vehicle goes up for public auction on Friday, as well, for 10 days.
