Courtney Love's Amazing Weight Loss

The 42-year-old former Hole frontwoman shocked fellow tourists at Maui's Kea Lani Resort this week when she hit the pool in a small string bikini looking surprisingly thinner. According to a source with Usmagazine.com, Love has lost 45 pounds in four months since she began drinking Isopure diet shakes last December. A source tells Us that she's also been forgoing carbs, eating fish, steamed veggies, and "doing lots of yoga."

"She's feeling like a different person," says the source, who adds that her goal is to lose 55 pounds altogether.
