Eminem & Rihanna Do The ALS Ice Bucket Challenge On Stage In Detroit

Dr. Dre had one of the more memorable ice bucket challenges we've seen thus far, and the hip hop mogul decided to pass the task on to Kendrick Lamar, Snoop Dogg, and Eminem. We saw K.Dot's video earlier in the week, and now Eminem has taken the plunge-- on stage at The Monster Tour no less.

That's right, Em got the very special honor of having Rihanna douse him in ice water, for which he quickly returned the favor. From the footage we've seen, it's not clear who the two stars have challenged, but chances are they've picked some high profile candidates.
