Eminem stole the show Day 1 at Lollapalooza 2014 in Chicago—and it wasn’t just because of how awesome he is.

The 41-year-old rapper surprised fans by bringing Rihanna onstage to sing three songs: “The Monster,” “Love the Way You Lie” and “Stan.”

RiRi, 26, and Eminem gave us a sneak peek of what we can expect to see at their upcoming tour that kicks off later this week—and boy is it going to be a good one!

“Thank you @Eminem and Chicago for letting me share this moment with you at #Lollapalooza,” Rihanna tweeted.

The two singers have been spending a lot of time together rehearsing. On July 29, Rihanna tweeted and Eminem Instagrammed a photo of them together.

The Monster Tour kicks off at the Rose Bowl in Pasadena, Calif., on Thursday, Aug. 7.
