Unlike the vamp she’s played for seven seasons on “Melrose Place,” new mom Heather Locklear gets itchy these days if she’s away from home for even a night these days. “We’ll go out together, to dinner, and both say, ‘We miss our baby. We have to go see our baby,'” said Locklear, who is married to Bon Jovi guitarist Richie Sambora. Their daughter, Ava, was born 15 months ago. Locklear, 37, says in the next issue of USA Weekend magazine that she’s particularly appreciative of her homelife after her first marriage to Motley Crue drummer Tommy Lee failed. “You have to have a bad one to appreciate a good one,” she reflects.
