Eminem and Rihanna are gearing up for their “The Monster” tour, which is set to kick off at the Rose Bowl in Los Angeles on Aug. 7. Em posted a photo of he and RiRi yesterday at rehearsals next to a mic and few instruments.

The theme of the tour comes from the pair’s collaborative smash hit "Monster" off of Em’s album The Marshall Mathers LP 2. Expect to catch them at one of these three cities: New York, Los Angeles or Detroit.
