The 'Call My Name' hitmaker said she eats in moderation days before a big red carpet appearance so that she can look as trim as possible, reported Contactmusic.
"I don't diet but I do watch what I eat and I exercise. I wouldn't choose to eat anything heavy such as rice or pasta a few days before I walk a red carpet. Everything in moderation," she said.
The 29-year-old brunette, who follows fitness guru-to-the-stars Tracy Anderson's workout method, said she does not have a signature style but will always add a feminine touch to her outfits.
