In October, Shields opened up to PEOPLE about how her daughters have helped her feel more confident - particularly when it came to body image.

"I was never skinny. I was always athletic which means you don't fit in the sample sizes," she said. "My daughters say I'm curvy. To them curvy is different. I watch them celebrate it. I'm learning from them and they always say you're better off with something that shows your body rather than a muumuu."
