On May 17, Rihanna proved again that she is one of the sexiest woman ever, posting that racy topless photo that surely twisted the knife in Chris Brown‘s heart just as effectively as any sort of overt diss.

RiRi posed with her back to the camera for the Instagram pic:

“C’s on my feet,” Rihanna wrote for the caption, alluding to her Chanel sneakers.

That we’d have hardly noticed since RiRi is posing, topless bare back front and center.
