The 41-year-old actress said she does not mind getting older and is excited about taking on different roles in Hollywood, reported Glamour magazine.
"Now that I'm getting older, people have stopped asking me about proving myself and started asking me whether I'm worried that I won't get any interesting roles any more - when, actually, older roles are the best roles for a woman," Diaz said.
The 'The Other Woman' actress said she has a very little vanity.
"I have very little vanity - but at the same time I'm incredibly vain. If I see a bad picture of myself in a magazine, I'm, like, whatever. But it's a funny thing being out in the world in the way that I am. You really have to keep yourself in check because it's easy to lose your head," she said.
