Kelly Osbourne Reveals Weight Loss Secrets

The newly slim and trim Kelly Osbourne is revealing how she took off the pounds and admits she got more flack when she was overweight than when she was a drug addict.

"I took more hell for being fat than I did for being an absolute raging drug addict," she tells Us Weekly. "I will never understand that."

After years of being unmotivated to take the weight off, ("It's hard to get out of a hole you've dug so deeply," she says), the 25-year-old has lost a whopping 42 pounds the old fashioned way -- by diet and exercise.
