Bristol Palin dishes about Levi Johnston and Meghan McCain in her new memoir, Not Afraid of Life: My Journey So Far (out today from William Morrow).

In the book, the teenage mother, abstinence advocate and Dancing with the Stars star tells the woeful story of how she lost her virginity. Gawker has more: “she lost her virginity on a camping trip while drunk on wine coolers … Apparently she woke up unable to remember the event, and was reminded only by hearing her then-boyfriend Levi Johnston bragging about it to his friends on the phone.”

Palin also complained about meeting the McCains. ABC.com has more: “Palin writes that the first time she met the 26-year-old daughter of Sen. John McCain, she ‘ignored us during the entire visit’ … Palin adds that she ‘had a sneaking suspicion I might need to watch my back.’ ‘Every time we saw Meghan, she seemed to be constantly checking us out, comparing my family to hers and complaining.’”
