her forehead allows her to encase 4 brains. they are all different colors. remember that game with the 4 lights that you had to press? thats her shit. one day, her brains linked together like power rangers to form a superbrain, and the superbrain shot a lazer beam of information straight to a genie in a lamp, buried 5,000 miles underneath the ocean. The genie granted her 3 wishes, but it took three tries for the wish to reach rhianna, due to her wall-of-china forehead. and niggas dont really know this, but aint no genie do-overs.
her wish was to meet jayz
she let her dick sucking abilities do the rest
and its all history...success fame and money
get you three more brains and you can be there too
