Bristol Palin reveals she lost her virginity while drunk

Palin reveals that she love her virginity to Johnston after she got drunk for the very first time on a camping trip with friends. She says she woke up alone in their tent with no recollection as to what happened the night before. 

After confronting Johnston about the situation, he told her they wouldn't have sex again until they were married. That didn't last long. 

Palin writes they had sex again shortly after the camping trip. Palin was shocked to learn she was pregnant because she was on birth control pills (prescribed to treat cramps) and took eight home pregnancy tests before truly believing she was pregnant. According to Palin, Johnston's reacting to the news was, "Better be a f***ing boy." Charming.

Johnston will be telling his side of the story in his autobiography (autobiographies for everyone!) titled "Deer in the Headlights: My Life in Sarah Palin's Crosshairs."
