Chris Pratt Raps Eminem -- IT'S AWESOME!!!!! (VIDEO)

Chris Pratt is UNBELIEVABLE! You gotta hear him take the challenge and drop a verse from Eminem's "Forgot About Dre." It's just insane.

Chris -- who owns the theaters with "Guardians of the Galaxy" -- was on "The Whoolywood Shuffle" on Shade45 when DJ Whoo Kid suspiciously questioned Pratt about his rap knowledge.

Pratt also takes a shot at Orlando Bloom.
