Renee hit the red carpet at Elle's Annual Women in Hollywood Awards at the Four Seasons hotel in California on Monday night, and sparked a flurry of 'plastic surgery' rumours after appearing to look dramatically different.
The star looked a world away from when she played her smash hit role, Bridget Jones (reminder below, as if we don't all watch it at least once a month).
While she hasn't directly addressed those rumours, she has responded to the media frenzy in an interview with People magazine.
According to Just Jared, she said: "I'm glad folks think I look different! I'm living a different, happy, more fulfilling life, and I'm thrilled that perhaps it shows.
"My friends say that I look peaceful. I am healthy. 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. Rather than stopping to recalibrate, I kept running until I was depleted and made bad choices about how to conceal the exhaustion. I was aware of the chaos and finally chose different things."
The actress called the buzz about her looks "silly" but added she decided to open up because "it seems the folks who come digging around for some nefarious truth which doesn't exist won't get off my porch until I answer the door."
She said that she has spent time focusing on being "still", making a home, loving someone (boyfriend Doyle Bramhall II), learning new things, and getting healthy.
Finally, Renee told People: "Perhaps I look different. Who doesn't as they get older?! Ha. But I am different. I'm happy."
Good for you, Renee.
