This is Palin's second child. She also has a 6-year-old son, Tripp, with ex-fiance Levi Johnston. Palin, 25, announced her pregnancy in a June blog post, a month after she ended her engagement to Dakota Meyer. "I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you," she wrote.

My heart just doubled
