'There is Something About Marry' star Cameron Diaz says despite being at her fittest at 41 she finds it difficult to age gracefully in a culture obsessed with youth.

In a chat with Oprah Winfrey on OWN, 'The Body Book' writer says she finds that women are harder on other women when it comes to growing in years.

"Our culture is obsessed with not growing into who you were really meant to be," observes Winfrey in a sneak peek at the show, reported E! News.

"This is true," said Diaz, adding, "And women don't allow other women to age gracefully. And we don't give ourselves permission to age gracefully."

Diaz agreed with Winfrey that most of the women are trying to be "back there" in the past. "And they're trying... For me I feel like if I it's almost as if we have failed if we don't remain 25 for the rest of our lives. Like we are failures. It's a personal... failure.

Like our fault that at 40 years old that I still don't look like I'm 25. Oh, I'm sorry. I apologize. I wasn't able to defy nature."
