Rihanna  and Eminem  had an unforgettable finale to their "Monster" Tour: back-to-back ALS ice bucket challenges! It all went down during their concert in Detroit on Saturday night. Despite closing his eyes in fear after noticing "extra ice" in the mixture Rihanna  was ready to dump over him, Eminem  manned up and took it like a pro, rising triumphantly from his seat to a cheering crowd. Rihanna, however, definitely got the shorter end of the stick. "I don't do this ice sh*t," she said before noticing the "f*cking pot," not bucket, being carried out by three people. Her hilarious reaction, which continued as Eminem closed out the concert, is priceless. See Rihanna and Eminem get soaked in the video above, and then be sure to catch up on the best ice bucket challenge videos , and find out who still hasn't gotten in on the charitable trend  sweeping the nation.
