Rihanna Talks 'Battleship' Training (PHOTO)

Rihanna is no stranger to violence on camera -- see her "Man Down" video for proof -- but in her first feature film role, she's taking it to a whole new level.

The singer stars in "Battleship," the Peter Berg-directed big screen adaptation of the classic board game. She plays a hardened Navy sailor that helps take on the aliens that threaten the future of the world, battling alongside Taylor Kitsch and Liam Neeson, amongst other big name co-stars.

She's already famously fit, but to get military ready, Rihanna had to kick it up a few notches.

"We worked with real military people, you know, people in the Navy, people who have fought in Iraq before," she told UGO.com in a long interview about the film. "They pretty much came and drilled me. This one man, Donald, he pretty much drilled me, yelled at me, cursed me, 'Ow!' Made me do pushups."

And while she's very tough, it was hard not to crack.

"I really want to say, 'F*ck you' right back, but then he probably would have thrown me through the window!" she joked. "I was so scared I just stood there and looked at him like, 'I swear I’m going to get it right, I swear, I swear, I swear I’ll be good.'"
