Rihanna is promoting her Monster tour with help from an unlikely source. The singer is enlisting Jenelle Evans, star of MTV's 'Teen Mom 2,' to help get fans to her show.

The video spot, which appears on Rihanna's Instagram, takes actual footage from 'Teen Mom 2,' in an episode where Jenelle famously says she can't fulfill her jail sentence because she has tickets to a Kesha concert.

"I really can't miss that concert. 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," she explains.

This updated version features Rihanna at the end in lieu of Kesha. "It's not just a concert," says Jenelle, at which point the clip cuts to a voice screaming, "It's Rihanna!"

The Monster tour also features Eminem. Tickets go on sale to the general public on March 28.
