Hilary Duff made a joke about being jealous of Carrie Underwood over the weekend. Both women are wives of NHL players, and Carrie's husband was recently traded to Nashville, where she happens to live. Convenient, right? But Duff's husband is in his first season with the Pittsburgh Penguins, while she's based out of L.A. It's easy to see why she would be jealous of Underwood.
