Renee Zellweger unveils new look

Los Angeles:  'Chicago' actress Renee Zellweger was unrecognisable at a recent appearance at an event and she says she loves her new look.

The 45-year-old actress has shot down plastic surgery rumours and said her happy life is the reason behind her different look, reported People magazine.

"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," she said.

"People don't know me in my 40s. People don't know me as healthy for a while. Perhaps I look different. Who doesn't as they get older?! Ha. But I am different. I'm happy," she added.

More relaxing activities and happy relationship with her boyfriend Doyle Bramhall apparently contributed to her new look. "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," Zellweger added.
