"Sometimes, I'll ask my sisters [Mariel and Cisley], 'Am I looking too thin?'" the Colombiana actress admits to Us. "I've always been slender, but the older I get, the more conscious I am of my body, for health reasons. I'm over-depriving it of nutrients it needs because I want to look good. Doing that will age you. I'm happy that, in my early thirties, the pressure of wanting to please others is dissipated. Now it's about being me."
