Rihanna — Twerkin’ Off to Drake Song

The following video of a twerkin” Rihanna will probably upset Chris Brown for two reasons:

1) It”s sexy … and she”s reportedly cut him off from tappin” that ass.
2) She”s twerkin to a Drake song … Chris Brown”s mortal enemy.

The footage was posted by one of Ri”s friends — showing the pop star gettin” down to A$AP Rocky”s song “F**kin” Problems” — which features Drake.

During the clip that was posted, Rihanna shakes her ass during Drake”s verse.

It seems to be a thinly veiled dig at Chris — considering he and Drake hate each other so much, they brawled at W.i.P. nightclub in NYC last year.
