(Cover) - EN Showbiz - Fergie says her fluctuating weight has led people to speculate that she is pregnant.

The Black Eyed Peas front woman is regularly admired for her womanly curves and honed figure. Despite her enviably frame, the songstress says her "fluctuating" weight has led to untrue rumours.

Fergie has admitted that she has a weakness for fast food outlets which are the reason behind her fuller figure at times.

"I think people think that I'm pregnant sometimes because my weight fluctuates. My problem is my discipline. I see a Jack in the Box or a DelTaco, and I will impulsively want it," she confessed in the July edition of Alure. "I'm a work in progress in that area. I gain and lose weight everywhere from the thighs up."

Fergie says despite her weight struggles, there is one part of her body she wouldn't change. The 36 year-old has learnt to embrace her "unique" facial features, in particular her nose.

"I've learned to love my nose because it's unique. It's interesting, and it just makes me a little different," she explained.

Fergie has revealed she likes to feel youthful. The stunning star says she wants to grow old naturally whilst still maintaining her sense of fun.

"I'm definitely young at heart, and I always will be, I'm just trying to age gracefully," she added. (C) Cover Media
