Just days after Jay Z and Beyonce rocked the crowds at the Rose Bowl in Los Angeles, it was Eminem and Rihanna's turn to wow audiences with their Monster Tour on Thursday (Aug. 8).

According to Billboard, Em and RiRi performed a 47-song set of their classic hit songs that included 'Stan,' 'Diamonds,' 'The Real Slim Shady' and their own duets 'Numb,' 'Love the Way You Lie' and 'The Monster.'

Eminem and Rihanna did perform separate solo sets but came together onstage when it was time for their duet songs.

The 'Stay' singer was looking fiery in her outfit, which was emblazoned with hot rod flames and she bared her midriff in a short top. Eminem, meanwhile, made his entrance in his usual onstage attire -- dark camo bomber jacket, black hoodie, cargo pants and Nike Air Max kicks.

Backed by a 10-piece band, which included a horn section, the duo's exchange onstage felt natural as if two buddies were just hanging out and the audience were just eavesdropping.

Finally, Eminem and Rihanna performed encores of 'Lose Yourself' and 'We Found Love,' respectively, before ending the three-hour show with their smash hit 'The Monster.'

The Monster Tour will hit MetLife Stadium next in East Rutherford, N.J., on Aug. 16 and Comerica Park in Detroit on Aug. 22.
