Beyonce -- My Body So Bootylicious ... For a Skyscraper

Beyonce's body ain't just a brickhouse ... it's a whole freakin' Australian skyscraper -- or at least it's inspiring one.

Famed design firm Elenberg Fraser has the greenlight to erect a 68-story building in Melbourne ... which it says copies ‘Yonce’s form in her “Ghost” video.

The firm says the Bey tower design isn't just for show (though, it clearly helps) -- it actually makes sense structurally. The final product will house 600 apartments and a hotel.

How long before someone asks for a room in Beyonce's ass?
