With the way she shakes her booty on stage it's probably safe to say Rihanna is a pretty confident and feisty lady.
But the singer, 25, shows off an even more powerful side to her personality in the trailer for her new film This Is The End – she is seen slapping actor Michael Cera hard across the face after he grabs her impressive bum at a party.
Ok, so when we say Rihanna is demonstrating her powerful personality in the promo, that's not strictly true because there may be quite a few cheeky chaps who try to grab her bottom on a daily basis and we doubt she smashes their faces in – she only punched Michael because she was acting and she was probably paid a load of cash to do it.
Right, so now we've cleared that up, let's establish exactly how our RiRi, whose boyfriend Chris has just revealed he's had sex on a plane, comes to smash Michael round the chops.
She's starring in a film alongside a whole host of other famous names including Jason Segal, Jonah Hill, Seth Rogan and Emma Watson who all, randomly, play themselves.
The gang are pals with James Franco (obviously), who also plays himself, and they become trapped at a party at his house while a series of cataclysmic events happen around them in Los Angeles.
Anyway, we digress, lets get back to the rather amazing Rihanna's behind. While everyone is having plenty of fun, a rather drunken Michael Cera stumbles up behind RiRi and gives her bum a right old slap.
The totally and utterly disgusted singer puts down her umbrella (she's not actually holding one but that's our attempt at a joke) and proceeds to wallop Michael round the face, shouting: “Don't touch my f****** bumper b****!”
However, karma soon comes back to bite Rihanna on the... erm... bumper as she meets a grisly end when the ground she's standing on collapses and she tumbles down into a deep black hole.
