Mega movie star Julia Roberts is never going to get Botox--she'd prefer to see how she'll age. "I want my kids to know when I'm pissed, when I'm happy and when I'm confounded," the 'Pretty Woman' tells Elle Magazine for its September issue. "Your face tells a story and it shouldn't be a story about your drive to the doctor's office."

The star of the upcoming flick, 'Eat Pray Love,' also talks to the magazine about family life with her husband, cameraman Danny Moder, and three kids, 3-year-old Henry and 5-year-old twins Phinnaeus and Hazel. PEOPLE has a sneak peek at the revealing interview.
