Julia Roberts may have gained 7 lbs. from eating bowls of spaghetti, gelato and decadent desserts in Rome while she filmed Eat Pray Love, but don’t expect to find her three children eating rich sugary foods at home.
“I’m a pretty strict mom when it comes to sweets,” the Oscar winner, 42, told PEOPLE at Tuesday’s Eat Pray Love premiere in New York City. “Even though I have such a sweet tooth myself.”
Roberts admits she only allows twins Hazel and Phinnaeus, 5, and son Henry, 3, to eat candy and junk food on special occasions. “You want sweets, ice cream and cake to be a great treat and a celebration,” she says. “Something that’s not everyday. I think this makes them appreciate it when they do have it.”
