A pair of designer pants gave Courtney Love the incentive to lose 52 pounds in four months, according to the rocker herself. Love has blasted reports she underwent gastric bypass surgery to help her lose the weight, insisting she achieved her new look thanks to 1,200-calorie Isopure shakes and fish and vegetables.

And her willpower was helped by her determination to squeeze into a pair of Todd Lynn trousers, which she wore to a Beverly Hills party on Monday night.

She told People magazine, "They're Todd Lynn, they're sample size, they're from the runway."

Love also explained why gastric surgery wasn't an option for her: "I'm not eligible for that. It's illegal for me to get that. You have to be 100 pounds overweight, you have to be grossly obese."
