With the highly anticipated "The Monster" joint tour being just around the corner, Eminem and Rihanna are adding the finishing touch to bring the best shows this summer.

The "Love the Way You Lie" duo is currently rehearsing for the upcoming concerts, as Em took to his Instagram account on Tuesday night to share a photo of himself and Rih during their rehearsals. "The Monster rehearsals," he wrote the following caption.

Although the image does not reveal much about what fans can expect from the tour, one thing that stands out is what the "Diamonds" hitmaker is wearing: A black graphic sweatshirt that has a monster printed on, mashing up her own eyes, werewolf ears, cartoon vampire mouth and the moon. The clothing piece also has "MONSTER" written across both sleeves in caps.

The Detroit rapper and the Barbadian singer have collaborated with London-based streetwear brand Trapstar to create the official tour merchandise, including the one in Slim Shady's latest Instagram picture.

The U.K. clothing company also announced its fashion collaboration with the pair on Wednesday, July 30, via Twitter and Instagram: "Trapstar is pleased to announce our collab with @rihanna x @Eminem for the Monster tour merchandise collection."

The trek is set to kick off at Los Angeles' Rose Bowl on Aug. 7 and to end in the "Berzerk" rapper's hometown of Detroit on Aug. 22.

Meanwhile, Marshall Mathers is up for seven nominees at this year's MTV Video Music Awards, including Best Hip Hop Video for "Rap God."
