Julia Roberts: It's 'Impossible' to Explain the Appeal of My Smile

Julia Roberts poses for the cover of Allure‘s October 2015 issue, on newsstands September 29.

Here is what the 47-year-old actress had to share with the mag:

On explaining the appeal of her smile: “Impossible. I don’t think it’s healthy or productive to self-analyze. The way a person smiles is the way they smile. It sort of becomes this thing: ‘Let’s see that smile.’ I can smile or I can not smile, but I can’t perform… I am a genuinely and deeply happy person, which, as life goes on, you realize what great fortune that is, to feel like you just have the natural chemistry of joy.”

On Hillary Clinton‘s presidential campaign: “It is a tricky little topic. For me, as a woman in this world with a family and a job … not that I think she would be ‘a president for women,’ but I think her point of view is critical in this time when we are 51 percent of the population, and somehow the paradigm shift isn’t really happening. I would love to see more of what she has to offer in service to this country.”

On if she’d go into show business if she were 18 today: “No, I don’t think I could. Maybe it’s because I’m not 18�”I don’t have the same kind of energy�”but it just looks exhausting.”
