Behold, The Dutchess

For pop star Fergie, life is good. A platinum album, movie deals, and a makeup contract. But there was a time when she could hardly leave the house, let alone imagine being a celebrity.

In a revealing interview with Allure, Fergie talks about overcoming her addiction to crystal meth:

"I had chemically induced paranoid schizophrenia," she says. "At one point I gave myself an ultimatum, because I was absolutely sure the FBI and a SWAT team were coming for me. I said, 'OK, if you walk through that door and they're not out there, then it's the drugs.'"

After a couple years, Fergie realized her choice was sobriety or a mental institution. So she went through therapy, attending Narcotics Anonymous meetings, and got a grip.

Joining the Black Eyed Peas in 2002 was healing. The combination of founder will.i.am's infectious music and Fergie's killer performance as the lead singer catapulted the quirky hip-hop group to mainstream superstardom.

Performing and dancing is only part of Fergie's fitness routine. She does some form of exercise daily -- walking on a steep upgrade, sit-ups, push-ups, stomach crunches; she's thinking of taking a course in pole dancing, which is "a really good workout" she says.

Although she admits she loves to flirt, Fergie loves being monogamous with boyfriend Josh Duhamel. Last Valentine's Day while on tour, Duhamel flew out to see her. "While we were at dinner, he had the room lit with candles, and rose petals all over the bed," she recalls. "We had champagne, chocolate-covered strawberries, whipped cream. It was very romantic."

Marriage, children? She thinks so. But right now, there is the prospect of more endorsements, more movies -- she had a small role in the "Planet Terror" part of the "Grindhouse" double feature, and is keen on expanding into romantic comedies.
