"My friends say that I look peaceful. I am healthy," Zellweger explained in the article. "For a long time I wasn't doing such a good job with that. I took on a schedule that is not realistically sustainable and didn't allow for taking care of myself.

"I did work that allows for being still, making a home, loving someone, learning new things, growing as a creative person and finally growing into myself," said Zellweger,"People don't know me in my 40s."

"Perhaps I look different. Who doesn't as they get older? Ha!But I am different. I'm happy."
