Talk about loving a challenge. Imagine being married to brooding, turnover-prone Chicago Bears quarterback Jay Cutler. Kristin Cavallari doesn’t need to imagine, as she’s been wed to the surly slinger since 2013. The 28-year-old Kristin starred on MTV reality show “Laguna Beach: The Real Orange County” for two seasons, while she was a student at Laguna Beach High, then later appeared on “The Hills” follow-up. The slumping Cutler may not have much success on the field…but at home, he must feel like a winner.
