Last night (Aug 23), The Monster Tour came to an end in Detroit. Rihanna and Eminem performed a second show at Comerica Park, the final one of the entire monster tour.

Eminem was nominated by Dr Dre to do the ALS Ice Bucket Challenge, a viral campaign to benefit awareness for ALS (amyotrophic lateral sclerosis), where a person dumps a bucket of ice water on one’s head.

At the end of the show, Eminem was reminded to complete the Ice Bucket Challenge on stage, which Rihanna helped out with, by emptying the bucket over him.

As the game follows, you get to nominate three people. Eminem realized this on stage and nominated rapper Denaun Porter who completed the challenge right away. Rihanna, who stood watching the rappers, didn’t get away from sitting on the wet chair and was the last person Eminem nominated.

After asking the audience if she should do it and complaining over the huge pot that her hairstylist Yusef and assistant Jennifer brought out on stage, the island girl sat down and accepted the challenge; ice cold water and lots of ice.

Straight after the superstars waved their final goodbyes to the audience and closed The Monster Tour. Great job Rihanna and Eminem, we’ll miss you touring together!
