Channing Tatum has taken it all off ... his head!
The "G.I. Joe" star was spotted at an L.A. office building with a completely buzzed head -- though no word yet on what the new look is for.
Tatum has two movies lined up right now -- one, "Magic Mike," where he plays a male stripper, and another, "Love and Honour," where he'll play a soldier trying to win the affections of Catherine the Great.
