Celebrities' Most Memorable Pregnancy Announcements

The announcement of Bristol Palin's pregnancy was shocking for two reasons: She was only 17, and her conservative mother had just announced her candidacy for Vice President. The Palins stated, "Our beautiful daughter Bristol came to us with news that as parents we knew would make her grow up faster than we had ever planned." They also announced her engagement to baby daddy Levi Johnston, although the wedding never happened.
