Rihanna and Eminem kicked off their joint tour in California on Thursday night (07Aug14), treating fans to a catalog of their hits and a number of expletive-laden onstage collaborations.
The pair unveiled their Monster Tour at the Rose Bowl Stadium in Pasadena, and they opened the first show with a pre-taped skit which showed the pop star visiting her rapper pal in prison and featured a cameo appearance from The Sopranos star Michael Imperioli as a guard.
Both stars thrilled the crowd with their hit singles, including Umbrella and The Real Slim Shady, and they teamed up for several new collaborations with Rihanna replacing Dido's vocals on Eminem's hit Stan.
The pair also covered Airplanes by B.o.B and Hayley Williams.
The show ended with a rendition of the pair's hit collaboration Monster.
