We learned all about how Sports Illustrated models keep in tip-top shape, as well as a healthy, homemade three-in-one dressing recipe that will keep your calories from piling up. We've helped brunettes figure out the perfect outfits to suit their hair color. Feelin' like you just want to stay home and eat cake? We crafted a flawless three-layer confection with the help of a baking pro. Check out all that and more in this week's roundup of the best of POPSUGARTV!
