Chelsea Houska admitted "we're getting there" today while snapping herself in a super-festive Xmas onesie. The "Teen Mom 2" star, 29, is nearly at the end of her fourth pregnancy, with Christmas Eve bringing the MTV face flaunting one giant, and very stunning, bump. Chelsea, who got kids Aubree, Watson, and Layne decorating Xmas cookies in their pajamas this afternoon, posted photos of her brood, but she kept a moment for a little solo action.
