The Dutchess, the first solo album from Black Eyed Peas' front woman, Fergie, is climbing up the charts.

As the gains popularity on her own, the singer has advice for others inside and oustide the music industry: Beware of crystal meth.

"It was the hardest boyfriend I ever had to break up with," Fergie said to Time magazine. "I dug deep as to why I got there. It's the drug that's addicting. But it's why you start doing it in the first place that's interesting. A lot of it was being a child actor; I learned to suppress feelings."

At least now the starlet has performing - and the selection of interesting outfits for awards shows - to keep her distracted and entertained.

"We're on tour," she said. "I have an hour and a half of performing every night and improvising. If there's a rafter, I can climb right on."

Fortunately, Fergie hasn't encountered the same problems in Britain with her name as Diddy has; despite a rather well known Duchess of York sharing it.

"She called me on the phone," said the Southern California-born singer (real name: Stacy Ferguson). "We're talking about doing some charity work together, building schools."
