Bet you didn't see this one coming.
Promoting her newly-announced Monster Tour with rapper Eminem, Rihanna posted on Instagram a classic clip of ... Jenelle Evans from Teen Mom 2.
Fans of the MTV reality series likely recall Jenelle whining to her lawyer that she couldn't go to jail because she has tickets to a Ke$ha concert.
Well, Rihanna posted that great Jenelle moment ... with a twist:
"I really can't miss that concert," Jenelle Evans laments.
"That's why I got all these feathers in my hair. I bought clothes for the concert. I set up hotel rooms for the concert. It's not just a concert it's…"
Cut to an announcer shouting, "Rihannaaa!"
Well played, Rihannaaa!
