When it comes to getting her booty groped, Rihanna doesn't play that. The singer makes a hilarious, albeit brief appearance, in the red band trailer for the all-star apocalyptic flick 'This Is the End.'

The NSFW clip starts off innocent enough with a party at James Franco's house. The Bajan singer makes her first appearance chatting with Jason Segel when a drunken Michael Cera gropes her butt. Rihanna's response is to return the favor and slap the crap out of Cera. "Don't f---ing touch my bum-bum, bitch!" she yells. Point, duly noted.

Sadly, Rihanna's time in the trailer is short-lived as she falls into a sinkhole that opens up outside of Franco's backyard. Even beloved comedians Aziz Ansari, Mindy Kaling and Segel fall to their deaths. Hey, it's the end of the world. Go figure.

This isn't Rihanna's first time up on the big screen. Last year, the 'Stay' chanteuse appeared in the action flick 'Battleship.'

As for the premise of 'This Is the End,' it's an end-of-the-world comedy about six friends who are trapped in a house after a devastating apocalypse. After suffering from cabin fever, the group eventually ventures outside of the home where their fate and their friendship are tested in a now uncivilized world.

The movie stars James Franco, Seth Rogan, Jonah Hill, Jay Baruchel, Danny McBride and Craig Robinson, who all play fictional versions of themselves. The comedy flick opens in theaters June 12.
