Justin Bieber has sent fans into a frenzy by staging a virtual treasure hunt for the chance to meet him.
The Boyfriend hitmaker has signed up as the new brand ambassador for Adidas, and to promote the sports brand he has launched a contest to find pairs of his sneakers 'hidden' on the internet.
In a video explaining the rules, Bieber says, "Adidas' NEO label made me these gold sneakers that I've been rocking on my tour. But here's the thing, we've been hiding pairs online that I need you to find. When you do, you can bring them to me in person. Find the first clue, and start searching!"
Sharp-eyed fans who locate photos of the shoes online must go to the Adidas Facebook.com page to enter a special code, and will then be in with a chance to meet the singer in Miami, Florida.
