Bristol Palin Dishes On Her Relationship With Levi Johnston In New Memoir

From the images of the young couple posted in the media throughout the 2008 Presidential election, it appeared that Bristol Palin and Levi Johnston were two teenagers who were crazy in love -- and expecting a baby.

But in her new memoir, Not Afraid of Life: My Journey So Far, Palin reveals that things with Levi were never what they seemed, as she details their relationship from their drunken "first time" together, to the moment she found out she was pregnant with their son, Tripp, now 2, and the engagement she refers to as the "middle finger" to her family.

According to the 20-year-old single mom, she lost her virginity to Levi Johnston on a camping trip, but it wasn't the memorable, romantic occasion she had always imagined it would be. Apparently, Palin's first time having sex coincided with her first time getting drunk -- on a camping trip.

And though she doesn't remember what happened, Bristol says that she does recall hearing Johnston as he "talked with his friends on the other side of the canvas," and his promise to her that the next time wouldn't be until they were married.

But, as Palin writes, it was not long before the couple became intimate again.

In 2008, when she found out that she was pregnant, Bristol claims that she had been taking birth control pills which were prescribed to her to alleviate cramps. It wasn't until the 8th pregnancy test that she was convinced that she was going to have a baby.

While she says her parents were supportive of her decision to have the baby, reminding her that it was important for her to continue with school, Bristol says that Levi's response to the news was: "Better be a f***ing boy."

It was her mother's introduction as John McCain's running mate that Bristol says "somehow legitimized" her relationship with Levis, but after baby Tripp was born in December of 2008, she was told via text that her beau had been cheating on her.

Levis admitted the "affair" and the couple mutually agreed to break-up, only to shock both of their families 18 months later when they announced that not only were they back together, but they were engaged.

It wasn't long after their engagement, however, that Johnston informed Bristol that he had gotten another woman pregnant, and the two ended their relationship for good.

Now, Palin describes her baby-daddy as a "gnat" who is "constantly spreading false accusations against our family," and cheated on her as "frequently as he sharpened his hockey skates."

Of course, this is all Bristol's account of the way things went down. Not to be outdone (or to pass up an opportunity to be in the spotlight), Levis Johnston's memoir, Deer in the Headlights: My Life in Sarah Palin's Crosshairs will be released this fall.
