The Proposal co-stars lost to New Moon's Robert Pattinson and Kristin Stewart, but that didn't stop Bullock and Johansson from locking lips, as the tradition goes for Best Kiss winners."Now that we have done that, can we please go back to normal? Because therapy is really expensive. Go back to making fun of me," quipped Bullock, who is going through a very public divorce with husband, reported cheater Jesse James.
