The 'Pretty Woman' actress, 46, feels there is enough work for everyone and she has never felt insecure, reported Contactmusic.
"I always feel like there is room for everybody. I don't consider myself really all that ambitious. When I didn't get a part - even when I was younger and needing to pay my rent, I would think, 'Oh, someone else got it. She's going to be so good.' I never felt sour grapes," Roberts said.
