QB Jay Cutler proposed to Kristin Cavallari by sending her ring in the mail. She tells E!, "It was so silly. I was in the airport, leaving Chicago. We had just spent however many days together and we were texting and somehow it came up, like, 'Oh, shall we get married?' We're like, 'Yeah, OK.' And then he sent my ring in the mail. So I actually had my ring sitting at home for a couple of weeks before I put it on."
