The 46-year-old 'August: Osage County' actress was asked by a director of a film that her facial marks be "taken off" as he thought they made her face look "dirty", reported Contactmusic.
"One director wanted me to have two freckles taken off because he said it made my face look dirty," Roberts said.
Mother of three kids, Roberts also feels that many old actress are deeply beautiful and their faces radiate because of confidence and self-assurance.
"I definitely think some of my older female peer group are deeply beautiful women. They have this thing that radiates from them. It's coming from this deep place of understanding who they are and what their purpose is. It creates a light," she said.
"I don't spend a lot of time in the mirror. I'm pretty efficient in terms of looking at myself and, to be honest, I don't think what you're talking about is a business demand - it's a cultural obsession," she said.
