Prince WIlliam DJ'ing Like a Commoner -- Is This What the Poors Are Doing These Days?

HOW DELIGHTFUL!

Looking like the uncoolest person on the planet, Prince William did his best poor person impression Wednesday, hitting the "decks" for some "spinning" in Australia ... and Kate Middleton was obviously his only biggest fan.

Big Will and Kate are currently on a tour of New Zealand and Australia, and today's stop was the Northern Sound System in Adelaide, where William got some DJ lessons.

After dropping some "fat beats," William then pulled a Bieber, hitting up a nearby skate park for some "tagging." Or whatever the kids call it.
