Black Eyed Peas star Fergie has opened up about the pressures of looks in not only Hollywood, but in the public eye. 

The 'London Bridge' singer graces the cover of July's issue of Allure magazine and explained that she's trying to avoid the lure of plastic surgery or physical enhancements:

"I'm definitely young at heart, and I always will be, I'm just trying to age gracefully."

"I gain and lose weight everywhere from the thighs up. I think people think that I'm pregnant sometimes because my weight fluctuates."

Speaking about her weight, Fergie added:

"My problem is my discipline. I see a Jack in the Box or a DelTaco, and I will impulsively want it. I'm a work in progress in that area."
