We can't think of a better collaboration!

Rihanna and Eminem took the stage at Sunday's MTV Movie Awards to perform their hit song "Monster", and the pair definitely rocked the house down!

The Barbadian bombshell and the Detroit-born lyricist were introduced by Orlando Bloom, and RiRi appeared before Slim Shady came out from behind flashing red lights and joined her.

We bet Drake was proud of his lady love!
