MINNIE DRIVER KEEPING BABY'S SEX A SURPRISE

"I'm old-fashioned," the actress, 38, said.

"Women for thousands of years have not found out," she says. "I couldn't base something that was so auspicious and beautiful of that moment, and take away the surprise for home décor."

"They say you lose your sweet tooth, which apparently means it's a boy, but I'm convinced the baby is a girl," says Driver. "I've kind of lost my sweet tooth, but my mum is like, 'No, you're fat like I was, and I only had girls.' She meant thick in my waist!"
