As you might expect when there is a huge sporting event in this country, the celebrities will be out in full force. Last night was no exception as Rihanna was there to cheer on the Warriors, even sitting with the owner. Floyd Mayweather and the money team were in the building as well along with Magic Johnson, Marshawn Lynch, Shaq & more. RiRi might have been cheering the Warriors during the game, but multiple reports said she was in the back screaming Lebron’s name multiple times post game. Her presence may also explain why JR Smith played so bad after their alleged dating stint in NY! Check the gallery.
