Rihanna went a little crazy on stage during the London show during her 777 tour, and it's all because her band was playing live!

I am beginning to think this Rihanna is a little wacky. Her tour rider was released the other day, and it sounds like a stoner's shopping list. Flaming Hot Cheetos, Oreos, Ruffles, Gummi Bears, and Cup O'Noodles, among other things. Now we get to see her go off on her band because they weren't playing LIVE in synch with her backing track! What a diva! At least they are actually playing instruments.
