Allure Cover Star Fergie Reveals the (Expensive) Secret to Her Amazing Skin

Fergie's sexy, tough-girl style may seem extreme at times, but no matter how long her extensions or how bare her midriff, she doesn't regret a single moment. By 2004, "I knew I was doing sexy," she told Allure's Judy Bachrach. "So I went for it." In our February issue, Fergie admits to one disaster involving at-home hair color that she'd rather forget and reveals her favorite skin-care products and makeup picks.

Her biggest hair regret: "It might have been in junior high—I wanted to dye my hair dark, so I put a rinse in my hair, and what came out was like a pea green. Awful! And my mom made me go to school with it till I got it professionally done. I had to go to school like Frenchy from Grease."

The makeup she loves the most: "A nice extended black eyeliner. I would always copy that Marilyn look in the movie Gentlemen Prefer Blondes and sing in the mirror. My grandmother used to look like Marilyn Monroe!"

Her best skin-care trick: "I do M.A.C. foaming face wash because it gets the skin really clean, then Eight Hour Cream by Elizabeth Arden and La Prairie neck cream. And the La Mer eye cream. I tested different neck creams and eye creams on tour with my makeup artist for, like, two months, and these are the ones that work best for me. Controlled testing!"

A typical breakfast: "A shake: kale, romaine, spinach, half a banana, half a pear, half an apple, a little bit of water, and a juiced orange in the Vitamix. It's changed my life. It's like a buzz. It gives me a little sugar boost, but it's all healthy sugar! I did it during my pregnancy. Axl Jack just loves it. We call it Green Goo."

The beauty treatment she would not want her husband to see: "I mean, he's walked in on me during my bikini waxing—and I'm like, OK, honey, hi.' And I'm on all fours.... But he doesn't just leave; he gets curious!"
