Rihanna has definitely evolved from classy to risqué. During the days when she was still blossoming in her career, the singer always looked chic and polished but today, she takes fashion into risky heights.

Last year, Rihanna was hailed as the "Sexiest Woman Alive" by Esquire magazine. She was also chosen by Vogue magazine to front their 10th annual shape issue.

However, the Barbadian singer confessed that for years she wasn't comfortable with her own skin and ironically enough, she revealed that the more she got naked the more she gets through her confidence issues.

"The more I got naked the more comfortable I felt. I just had to face my fear," the singer said on Women's Fitness magazine.

While still overcoming her issues, Rihanna managed to sell more than 60 million singles and 25 million albums worldwide which makes her one of the top selling artists of all time. And just about when her fans think they've seen everything from her, she makes her first acting role in the film "Battleship" along with Taylor Kitsch and Liam Neeson.

"You always find something wrong, you always find something you're uncomfortable with, and one thing turns into another and you get embarrassed and self-conscious about it," she shared.

"It was just knowing my body is the way it is no matter what that helped me, knowing that it is what it is under clothes or outside of clothes."

Rihanna also acknowledges that her way to resolve her body issues might not probably work for everyone else. She also admits that to keep herself fit, she keeps track of her work outs in preparation for her movie role.

"I had to do a lot of physical training with a personal trainer as well as a soldier, and it was gruesome, but fun," Rihanna said. "One man drilled me, yelled at me, made me do push-ups. It really got you in the mentality. The weapons were really heavy, so at times I had to hold a 5lb sandbag just to get used to drawing it the right way."

Although her usual exercise got amped up, the 24-year-old singer said that she indulges in a few guilty food pleasures every now and then.

"My favourite food right now is microwave butter popcorn," Riri said. "And when I'm in London I'm close to authentic Jamaican food, so I tend to eat that every day."
