Michael Cera asked to slap Rihanna's butt for real and everything else you need to know about 'This Is the End'

The upcoming apocalypse film This Is the End focuses on a gaggle of celebrities that show up for a party at James Franco's house and then THE BIBLICAL APOCALYPSE STARTS. It stars James Franco and Seth Rogen and Jonah Hill and Jay Baruchel and Craig Robinson and Danny McBride and Jason Segel and Michael Cera and Rihanna and Emma Watson and Aziz Ansari and Kevin Hart and Mindy Kaling.

And, if "apocalypse during James Franco's party" didn't convince you to see this film as soon as humanly possible, then GQ's Q&A with the cast will certainly take care of that for you. Seriously, because...

Michael Cera asked if he could slap Rihanna's butt, fo realz.

Cera: In the script, I think it just says, "Michael Cera does a line of cocaine and slaps Rihanna on the ass. And she turns and slaps him back."

Goldberg: And Michael said to all of us, "I'm going to ask her if I can slap her butt for real. I think it will make the joke way funnier."

Masturbation?

Franco: So there was this scene in the script where Danny was supposed to have masturbated on my Penthouse and ruined it.

James Franco negging himself?

Franco: Your Highness? That movie sucks. You can't get around that.

The whole Q&A focuses on how the movie came about, the filming process, what it's like to be on set with a group of famous people who are actually real-life friends (insert Illuminati joke here), and why This Is the End will probably be the funniest movie you see this summer. We're basically in line already. [GQ]
