The wave of the ALS Ice Bucket Challenge continues, joining other celebrities in support of the great cause is Eminem and Rihanna. The superstar duo took time out from their The Monster Tour in Detroit to answer the call of celebrities who have previously been doused in the icy water.

During the ALS portion of the show, Rihanna poured the icy water over the head of Slim Shady before finding herself on the receiving end of a bucket by a couple of stage staff members. Eminem has passed the challenge along to Rick Rubin, Mr. Porter and Rihanna, who took care of the challenge at the show. Check out the video of their challenges in the tweet below.
