As a co-host of Dancing with the Stars, she's got to be in fighting form. But the mom of four takes it all in stride (often in her Skechers Shape-Ups, for which she is a spokesmodel). Burke admits to working hard to maintain her figure, but says in the end, being 40 is just a number – her attitude is what matters. "It's really about being comfortable in your skin at every age," she told Shape. "I feel better now than I ever have before. I feel stronger, I feel more confident, I feel healthier. I feel like I know my body better."
