Rihanna looks exceptionally demure and far from her usual thug look as she attends a photocall for her debut movie "Battleship." She also denies dating rumors with Ashton Kutcher and confirms she is currently single.

The 24-year-old often seen in unlikely and revealing ensembles showed up at a photocall in London looking polished and sophisticated. She wore a ladylike, knee-length dark olive dress which accentuated her slim figure. Rihanna even managed to upstage Brooklyn Decker with her old fashion class.

The look she donned was definitely a far cry from the recent Twitter image she posted the same morning. Rihanna also boasted about the sunny weather in London which must have put her in a good boost.

Talking about her most recent rumor with Two and a Half Men star Ashton Kutcher, the Barbadian singer said she was single and happy.

Rumors sparked that the two must be dating since Riri was snapped leaving Kutcher's house at 4 o'clock in the morning.

"You're so good at connecting with people that I think that we actually feel we know you. Things are clearly going brilliantly in your career. I just wondered if you are as happy in your private life, and will we see a certain Mr. Ashton Kutcher perhaps making a trip over here?" a British reporter asked the singer wherein she became defensive after.

"Wow, how disappointing was that question?" the "We Found Love" singer said. "I'm happy and I'm single, if that's what you're really asking."

Although she sounded a bit upset when asked about the rumors, she was clearly beaming with smiles when photographed with co-star Brooklyn Decker. The two girls were seen laughing as they were obviously happy to see each other again.
