See Rihanna And Eminem Take Ice Bucket Challenge On Stage
R&B princess gives rapper a soaking before she gets drenched in front of crowd herself...
WARNING: Video contains strong language.
The pair undertook the charity ordeal on stage at the final night of their joint The Monster tour in Eminem's home city of Detroit.
It seems Slim Shady was the first to get drenched, sitting on stage as his hype man Denaun Porter whipped the crowd into a frenzy - and then Ri-Ri upended a bin full of water over him.
He leapt up and walked it off for a few second before telling the crowd that it was "so f**king wet man".
And he passed the challenge on to Rihanna, who stayed seated as a group of flunkies emptied what looked like very icy water over her head.
They're not the only celebs to have picked up the baton in the last day or so however - with Kylie Minogue also accepting the challenge from Ricky Martin and Benedict Cumberbatch.
She took it alongside fashion maestro Stefano Gabbana on what appeared to be a luxury yacht somewhere nice and sunny.
After pouring their ice buckets, she began prancing around singing: "That feels so good, so good, so good."
