*Rihanna promoted her new Monster Tour with Eminem over the weekend with the help of a clip from MTV’s “Teen Mom 2” that went viral in 2012.

On Saturday (March 22), the singer Instagrammed cast member Jenelle Evans telling her lawyer she couldn’t go to jail because she had to go to a Ke$ha concert.

“I really can’t miss that concert,” Evans, 22, explains in the clip. “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…”

And at that point RiRi added in an announcer’s voice shouting, “Rihannaaa!”

Evans retweeted Rihanna’s video on her Twitter page, writing, “dude Rihanna actually noticed me lol.”
