Rihanna says appearing in Battleship has made her fearless.

The 24-year-old singer makes her acting debut opposite Taylor Kitsch and Brooklyn Decker in the movie and identified a lot with her character Petty Officer Cora Raikes.

"Definitely, I'm a fighter. I was able to identify with the character in lots of ways. She's tough and focused. But embodying her also helped me to become more fearless. I had an incredible experience on Battleship. I learned a lot about myself. I had to ask myself a lot of questions to get in touch with the right emotions. And it was great working as a team, for the first time in a long while it wasn't all about me."

Rihanna admitted she has always wanted to star in an action movie and is delighted by the finished movie: "Funnily enough, action was what I wanted to do. It seemed badass and cool. I didn't imagine I'd be fighting aliens, but Battleship was a great way to get into movies and it was a role I could do. I was blown away when I saw it. It's really fun."
