Bajan beauty Rihanna recent shot a cameo for a film called 'This Is The End', which is funny man Seth Rogen's directorial debut, and she had to slap one of the actors across the face.

Michael Cera, who starred in 'Superbad' and 'Scott Pilgrim vs. the World', had to work on a scene where he hit Rihanna's backside and she gave as good as she got by hitting him back. Rogen told MTV:

"Rihanna did slap the s**t out of him. For real, he said, 'I'm actually going to slap the s**t out of your a**,' and she was like, 'I'm actually going to slap the s**t out of your face then.'"

"We did it like six times, and the last time, he was like, 'I don't think I can do this anymore.'"

Rogen also opened up about how he decided to recruit Rihanna for the cameo and added: "I'd never met her before we made this movie. I read that some of her favourite movies were Superbad and Pineapple Express, and I just remembered it to make me feel good about myself. And then, years later, we were doing this and we were like, who could we get? And I was like, 'Rihanna!'"
