Courtney Love posed for the upcoming issue of Harper's Bazaar wearing a hat, jewelry and shoes.

"Go check it out. All of the size 8s are gone," the 43-year-old singer tells the magazine in its September issue, on newsstands Aug 21. "I've lost a lot of weight, and I have done it through being quite disciplined."

Love says she now weighs about 139 pounds. She credits her new figure to visits to a clinic for "colonics and fasting" several times a year and eating a daily diet of two meal replacement shakes and "fish and macrobiotic food."

"Some people think it's about weight loss, but it's about detoxing," says Love, who underwent a lifestyle change after packing on pounds last year.

The former frontwoman of the rock band Hole — and widow of Nirvana singer Kurt Cobain — blames the weight gain on a bad breakup and eating too much macrobiotic food.

"My daughter (Frances Bean) and I were kind of going for it because the dessert's fantastic," she says. "I put on 30 pounds, and I put on another 15 out of emotional depression. Then I finally get an Italian Vogue cover, and I'm 182 pounds."

"By the way," she adds, "I hate reading magazines where the actresses are saying, `Broccoli and fish, broccoli and fish.' You liars. You bulimic liars."

Love, whose last stint in rehab was about two years ago, is trying to leave her troubled past behind.

"For many years, I took pills. I felt like I had this dirty secret," she says.
