Bristol Palin is opening up about her ex-fiance Levi Johnston, losing her virginity and her mother Sarah Palin’s vice presidential run in her new memoir "Not Afraid of Life: My Journey So Far."
Among the most personal details Palin reveals is the story of losing her virginity: The 20-year-old writes that she was on a camping trip with Johnston and drank too many wine coolers. She later woke up in the tent alone and could hear Johnston talking with friends outside. She had no memory of what happened.
They both vowed to wait until marriage to have sex again, but that didn't hold. When she got pregnant with their son Tripp, it took eight at-home pregnancy tests to convince her it was really happening, she said. She had been on birth control for cramps and never expected to conceive.
According to Palin, Johnston was less than supportive, saying, "Better be a (bleeping) boy."
Much of her history with her ex-boyfriend, who posed for Playgirl after their split, overlaps with her mother's run for vice president in 2008. In the book, she relives the family’s trip to Dayton, Ohio, where then-Gov. Sarah Palin announced she would be running alongside Sen. John McCain (R-Ariz.), and to the GOP convention, where the media found out Bristol was expecting.
Johnston was along for the ride, and Bristol explains that in her mind, having him there "somehow legitimized us as a couple.”
However, soon after Tripp was born things fell apart. Not only was Johnston cheating, but she and her family found out he was blabbermouth too.
The way she sees it, he is "the gnat named Levi Johnston constantly spreading false accusations against our family” and the guy "who cheated on me about as frequently as he sharpened his hockey skates."
Despite their ups and downs, the two did try to reconcile briefly. He proposed and the couple sold their engagement story to Us Weekly, but they quickly split. It turned out, she writes, that Johnston told her he was having another baby with someone else.
This time they stayed apart. "I'd just made a complete fool of myself and given my family the middle finger," she says.
Since the break-up, Palin has competed on "Dancing With the Stars," worked as a spokeswoman to help prevent teen pregnancy (and made some serious dough doing it) and even has her own reality show coming up on the Bio channel. In her eyes, she's "just a normal girl who couldn't hide her problems and learned a few lessons along the way."
However, more problems with Johnston loom: His book, "Deer in the Headlights: My Life in Sarah Palin's Crosshairs," is due out in the fall.
