Ooooh, this is gonna make Donald Trump so angry... which means it's a good thing!!
And boy, are they ever!!
What we would've given to be a fly on the wall at that club!
That is seriously one seXXXy trifecta!
One spy at the club said they saw:
"Rihanna and Katy doing a bump-and-grind dance together that was one step away from a lesbian love scene!"
The spy continued to explain that while the dirrty dancing went down, The Wolf of Wall Street star stared longingly as the two danced on each other!
But that wasn't the end of the cuhrazy shenanigans! Apparently Leo called for 15 bottles of bubbly for his A-List pals and they raged the night away until 5 a.m. the next day!
LOLz! Now THAT is what you call a normal Friday night for the stars!
