Singer Rihanna turns to acting.

The global pop star hopped aboard the USS George Washington aircraft carrier near Tokyo to promote her Hollywood debut film "Battleship".

"I think it's really special, and we look up to you so much. You're such an inspiration to all of us. We can never ever fill your shoes and we don't take it for granted. So, thank you for even letting us come onboard and be a part of your world for even this short moment."

The $200 million U.S dollar feature film based on a Hasbro board game, centers around a group of international naval fleets forced into war with alien intruders.

Victoria's Secret model-turned-actress Brooklyn Decker plays the female lead and hopes the film will shed a positive light on the military.
