Hollywood star Julia Roberts has vowed never to get Botox as she wants her children to be able to be able to easily read her emotions.

“I want my kids to know when I’m p***ed, when I’m happy and when I’m confounded,” she said in an interview with Elle magazine. “Your face tells a story and it shouldn’t be a story about your drive to the doctor’s office.”

Roberts, who is currently the face of luxury beauty brand Lancome, has said she doesn’t fully understand the obsession with looking young.

“It’s unfortunate that we live in such a panicked, dysmorphic society where women don’t even give themselves a chance to see what they’ll look like as older persons,” she commented. “I want to have some idea of what I’ll look like before I start cleaning the slates.”

Roberts has recently shot a new film, ‘Eat, Pray, Love’, and the actress has admitted that she put on 10lbs whilst filming the role. The story involves a lot of eating pizza in Italy, and surprisingly, Roberts really did eat it all – sometimes as much as ten slices of pizza a day.

“Like in the scene with the pizza, by the time the scene is over, I’ve eaten the entire piece,” she told Entertainment Weekly. “When we were in Naples, we started shooting at eight in the morning, and I think by 8:45 I’d eaten eight or ten pieces of pizza. Pizza was what I ate all day that day.”

However the weight gain was not unexpected – it was, in fact, planned. In the book, the main character gains weight in Italy before heading off to India and Roberts has followed the book’s plot.

“I could have used a bigger pair of jeans when I went off to India!” Roberts exclaimed.
