While rumors of a new single spread across the Internet, Rihanna is already beginning work on the set of her feature film debut in "Battleship." Photos of the Barbadian songstress surfaced online yesterday showing a brunette [article id="1644484"]Rihanna[/article] dressed in character.

Donning a traditional U.S. Navy getup with gloves and work boots, the singer was spotted in Hawaii on the set of the Peter Berg-directed science-fiction movie, wearing a nametag with the name "Raikes." The board-game adaptation is the story of naval officers who use Earth's ships to fight against alien intruders.

According to one of Rihanna's latest tweets, the singer is scheduled to continue work in Hawaii for two weeks. "HAWAII...Hawaii...hawaii......who wouldn't want to work here for 2 weeks," she tweeted, along with a photo of her posing on a balcony.

In addition to the pop star, the film's cast lineup includes "True Blood" star Alexander Skarsgård, Taylor Kitsch of "Friday Night Lights" and bombshell supermodel Brooklyn Decker.

[article id="1646913"]Skarsgård told MTV News[/article] that the film will be "quite different from the board game," and added that he doesn't think "Battleship" will follow the latest trend of filming in 3-D. Skarsgård will play a commander of one of the Navy destroyers in the film.

Universal has set "Battleship" for May 18, 2012, release.
