This is the first child for Kristin and her fiance Jay Cutler, but No. 2 is already in the plans. Kristin told Glamoholic, "We were talking about the possibility of having another kid right away and then getting married so we can have two kids close in age. We want four kids, so we're thinking maybe have one more, then get married, then have two more. But we'll see -- it all depends on how the first one goes."
