Bieber dons Oilers jersey given to him by Gretzky

Looks like the Edmonton Oilers may have gained a fan.

Justin Bieber took the stage in Las Vegas for a concert wearing an Oilers jersey Friday night.

The jersey appears to have been a gift from Oilers great Wayne Gretzky, who snapped a picture with Bieber and the signed jersey.

But it's pretty clear who the Great One in the picture really is.
