Eminem and Rihanna opened their six-date joint "The Monster" tour at Rose Bowl in Pasadena, Calif. on Aug. 7, Thursday with 50 songs, Idolator reported.

During their opening show, Eminem repeatedly and profanely told the audience at the packed Rose Bowl stadium that he does not much care about anything.

The two performed solo material and collaborations for three hours including a mash-up cover of Jay Z's "Run This Town" with "Renegade" verse from Eminem, Consequence Of Sound has learned.

Opening the show with "Numb" and "No Love (Don't Hurt Me)," Rihanna was dressed in a black track suit laced with orange flames while Eminem was strapped to a hospital bed in his signature gray hoodie.

For almost an hour, Rihanna revisited her set list from her Diamonds World Tour in 2013, most of the songs of which are from her 2012 album "Unapologetic."

Included in her mini set are "What Now," "Phresh Out the Runway," "Birthday Cake," "Talk That Talk," "Rude Boy," "What's My Name" remixed with Trey Songz' "Na Na," "Pick It Up," "Cockiness (Love It)," Man Down," "Umbrella" and "Love the Way You Lie" among others.

For his mini set, Eminem performed "3 a.m.," "Square Dance," "Business," "Kill You," "Evil Deeds," "Rap God," "Marshall Mathers," "Criminal," "The Way I Am," "Like Toy Soldiers," "Forever," "Berzerk," "Cinderella Man," "My Name Is" and "The Real Slim Shady" among others.

Performing with Mr. Porter, Eminem was casually dressed in a white T-shirt and camouflage shorts.

Aside from Jay Z's "Run This Town," "Numb" and "No Love," the two also performed T.I.'s "Live Your Life," "Crack a Bottle" and "Won't Back Down" together, Gigwise reported.

Prior to their joint tour, Rihanna took to Twitter to share a photo of her with the 41-year-old Detroit rapper during the rehearsal captioned, "Marshall! @Eminem #MONSTERtourRihearsals #Detroit."

Eminem and Rihanna are set to perform in Detroit on Aug. 22 and 23, Detroit Free Press reported.
