Rihanna to Lend Voice to Animated Film "Happy Smekday!"

Photo by Michael Becker/FOXRihanna's movie career is moving along. After making her big-screen debut in the sci-fi action thriller Battleship, she's now set to lend her voice to an animated film called Happy Smekday!, according to the Hollywood Reporter.  Jim Parsons of Big Bang Theory fame will be her co-star in the movie, which is based on the award-winning book The True Meaning of Smekday.

In the film, a friendly alien race uses Earth as a hideout from its enemy.  But when one of the aliens accidentally blows their cover, he has to go on the run with a teenage girl.  The two set off on a cross-country trip during which they both learn what it means to be human.  Parsons plays the alien, and Rihanna plays the girl.

Rihanna also recently filmed a cameo in the new comedy The End of the World, directed by Seth Rogen.
