The 36-year-old singer insisted that when it comes to healthy eating, she won't ban any foods completely and said she enjoys everything in moderation, reported People Magazine.
"I don't deprive myself of anything. I have everything in moderation," she said.
The "Poison" hitmaker, however, said she refrains from eating mid-night snacks when she is watching her weight.
"When I'm really watching my weight, I refrain from eating late at night."
The singer also revealed she drinks up to eight glasses of water a day and enjoys yoghurt and granola for breakfast and a pasta dish for dinner.
