This tells me two things.
1- JR Smith took some time out to see what Rihanna was saying about him on Instagram
2- JR was ready for the question.

It is important that he takes the high road, because if the Knicks have any chance to win the series, they need his head in the game, not at the club and definitely not on Rihanna.
