Fair warning — this is gonna make some of U sicker than the morning after a frat pAArty!!
While all eyes were on him on the main stage in an Orlando nightclub, the DJ decided to play RiRi's smash hit.
And instead of being a bashful Breezy, he took his dancing up a notch and sang the entire song!!
Club Vain went WILD!!!
We know a lot of people think the song is Rih's love letter to him, but we wanna know what U think!! Is this another sign of their rumored reconciliation???
