Melrose vixen can't gain an ounce

HEATHER LOCKLEAR won't get one ounce of pity from other women for her "weight" problem: The stick-thin star stuffs herself with high-calorie goodies but never puts on a pound.
     "It's impossible for me to gain weight!" says the 5-foot-4 Melrose Place vixen.
     "I can't get fat, even if my life depended on it. I've never been on a diet or been overweight. In fact, I have to eat high calorie foods just to keep my weight up to 104 pounds.
     "I know that's gonna make a lot of women hate me - and I don't blame them. I guess I'm just one of the lucky ones!"
     Even when she was pregnant with now 9-month old daughter Ava, hot-body Heather was back to her pre-pregnancy size 2 within a week.
     "And that was without dieting or exercising," says the 36-year-old star, who's married to Bon Jovi guitarist Richie Sambora, 39.
     But unlike most women who would be thrilled, Heather wasn't happy. "I was hoping the curves would last after the baby was born," she says.
     I loved being pregnant. I was 134 pounds and felt curvaceous and sexy. My breasts were large and my hips were round. It was a new experience for me."
     But ever since giving birth she's been back to shoveling down calorie-packed goodies.
     "I eat junk food, drink Coke and I love ice cream and chocolate cake," Heather says. "It would be a big lie if I said I like spinach salads.
     "I'll never write a diet cookbook, that's for sure!"
