This is so sweet! As you know, I'm from Chicago! I love this! I have loved Kristin since the days of Laguna Beach. There is always something about the feisty, tell it as it is girl that I love from reality TV. She always seemed so real and cool. Except obviously the last episode of the Hills when she proved some of the show was fake. :( Either way I love this "real" relationship. Plus whatever she has done-our guy Jay is doing amazing! I hope she gives him some good luck for our game this weekend against the Packers! I'm for sure Team Kristin and Jay!!!
