The Slim Shady gets a bucket of ice cold water dumped over his head first before RiRi gets drenched afterwards.
Eminem and Rihanna capped off their "Monster Tour" with ALS Ice Bucket Challenge. The crowd roared as the Detroit rapper and the Bajan R&B singer got drenched live on stage Saturday, August 23 at Comerica Park in Detroit, Michigan.
RiRi, wearing a black sport bra and neon-green pants with suspenders, did the honor of dumping a bucket of ice cold water on the Slim Shady's head as he took the challenge first. The Barbados singer went next with crew members pouring water on her.
The two join a growing list of celebrities taking the Ice Bucket Challenge such as Bradley Cooper, Liam Hemsworth, Kristen Stewart, Reese Witherspoon, Chris Martin, Gwyneth Paltrow, Josh Hutcherson, Tom Hanks, Benedict Cumberbatch, James Franco, Chris Evans, Chris Hemsworth, and Kelly Clarkson.
