You can add Eminem and Rihanna to the long list of celebrities who have taken part in the ALS Ice Bucket Challenge.

The two megastars were in Em's hometown of Detroit for the second night in a row with their co-headlining Monster tour, and took time out of the performance to answer all the Ice Bucket Challenges they'd received. 

Slim Shady had RiRi do the honors to start things off and after he was drenched, Rihanna took the seat and had a few of her friends douse her in the bone chilling water.
