Eminem and Rihanna have participated in the ALS Ice Bucket Challenge, a trend that is meant to increase awareness regarding ALS (amyotrophic lateral sclerosis), otherwise known as Lou Gherig's Disease.
The two stars had ice dumped on their heads on stage.
Rihanna dumped the ice on Eminem's head as the emcee sat in a chair. Rihanna had ice dumped on her head shortly after.
Eminem called out Rick Rubin to participate in the challenge, also, according to Billboard.
The rapper and singer have been touring together as part of their The Monster Tour, a run that ended last week.
