The Barbados-born singer says girls should always make an effort when selecting their lingerie, because you don't know who you may be disrobing in front of.
She said: "This winter I am loving houndstooth, lace, silk. I would say always wear some sexy lingerie under your clothes. Even though you have to be all bundled up, you'll look cute when you take it off."
The "Russian Roulette" hitmaker – who is currently single - also revealed she struggles to maintain her super-sexy figure, and has to limit her intake of certain foods.
She added to more! magazine: "I should be on a low-carb diet. My genetics say that I shouldn't have carbs at all, but 'm not a disciplined eater unless I have something big coming up like a photo shoot or video. I'm still having a hard time being a healthy eater."
