Kelly Osbourne checked into rehab for drug and alcohol addiction three times.
But the singer, 25, tells the new Us Weekly (on newsstands now): "I took more hell for being fat than I did for being an absolute raging drug addict. I will never understand that."
The 5-foot-2 Osbourne, who once weighed "almost 160" pounds, recalls walking down the street one day and "some horrible obnoxious teenager screamed out a car window to me, 'You're fat!'" she tells Us Weekly. "I went to my parents [Sharon and Ozzy] bawling, 'I would rather be called ugly than be called fat!'"
She tells Us Weekly she "hated" herself because of her weight and "never wanted to do anything to fix it … For a very long time, Mrs. Field's salted cookies were my favorite thing in the world … It's hard to get out of a hole you've dug so deeply."
Today, after years of yo-yo dieting, Osbourne has lost 42 pounds the healthy way — through regular exercise and a portion-controlled diet.
"I'm really proud to look in the mirror and not hate every single thing I see," she tells Us Weekly. "I no longer think, Why don't I look like this girl or that girl?"
