J.R. Smith and Rihanna have a feud. That sounds pretty ridiculous, but it's true.

The friction between the New York Knicks guard and the recording artist's began May 8, 2013. One day after the Knicks beat down the Indiana Pacers 105-79 in Game 2 of the Eastern Conference semifinals at Madison Square Garden, a photo surfaced showing the two at a New York club for Rihanna's Diamonds World Tour After Party . Smith can be found over Rihanna's left shoulder.

At the time, the Knicks knotted the series at 1-1 and had three full days off. The series took a turn for the worst in Indiana, though. The Pacers won both Games 3 and at Bankers Life Fieldhouse to go up 3-1.

With Game 5 looming and Smith struggling -- the 2013 Sixth Man of the Year averaged 14 points in Games 3 and 4 -- Rihanna lashed out on her paparazzi partner on Instagram. Here's a comment captured by Larry Brown Sports:

The Knicks lost the series in six games. Smith had an abysmal 2013-14 season and the Knicks missed the playoffs.

This did not stop Smith from taking a shot at Rihanna on Monday.

The caption reads, "Lmfao #greatmorningworld," but the meme text is what matters. The message is clearly a mockery of Rihanna following LeBron James, who played for the Miami Heat from 2010-2014. James signed with the Cleveland Cavaliers, his first NBA team, over the weekend.

Rihanna has seven Grammys. J.R. Smith's only professional All-Star Game appearance came in the Chinese Basketball Association.

Despite the comparison, it is perhaps to no one's surprise that Smith would take a shot at a much more successful individual. Besides, when has Smith ever passed up a shot, ill-advised or not?
