Rihanna will take on her first animation film role in Happy Smekday.
The You Da One singer and Big Bang Theory actor Jim Parsons will lend their voices to the lead roles in the upcoming DreamWorks animation about a friendly alien race who invade the Earth in order to hide from their enemy.
Tim Johnson — who directed popular animation films Antz and Over The Hedge — is on board as director and Tom J. Astle and Matt Ember are writing the screenplay.
The comedy is an adaptation of Adam Rex's popular book The True Meaning of Smekday. The plot will see an outcast alien (Parsons) go on the run across America with a human girl (Rihanna) after he accidentally informs the enemy of the aliens' whereabouts.
Rihanna (24) made her acting debut earlier this year with a role in action flick Battleship alongside Liam Neeson.
The Barbados-born beauty is hoping for a glittering film career and now plans to juggle movies and music.
She said earlier this year: "I didn't know if I would like it or be good at it. I really enjoyed the experience and I want to do more, try different types of roles so that I can see what I excel in most or like best."
Two-time Emmy winner Parsons has done voice-overs for several shows, including Family Guy and iCarly.
Happy Smekday is scheduled for release in late 2014.
