Zap2It: Bristol Palin's memoir 'Not Afraid of Life' dishes on McCain family, Levi Johnston and more

Bristol Palin, oldest child of potential 2012 presidential candidate Sarah Palin, has a memoir out titled "Not Afraid of Life: My Journey So Far," where the 20-year-old dishes her true feelings about Levi Johnston, the McCain family and more.

ABC News has a preview of the book, where Palin writes of John McCain's daughter Meghan McCain, "Every time we saw Meghan, she seemed to be constantly checking us out, comparing my family to hers and complaining. Oh the complaining."

She says Cindy McCain offered to be godmother to her son Tripp. "I had just met her and I wondered why she wanted any type of guardianship over my child ... I'd never seen people with so much Louis Vuitton luggage, so many cell phones, and so many constant helpers to do hair and makeup."

Of her "Dancing With the Stars" experience, Bristol writes, "I noticed some of the contestants rolled their eyes when they realized we'd survived to dance another day."

And of baby daddy Levi Johnston, Bristol calls him a "gnat" and says he "cheated on [her] about as frequently as he sharpened his hockey skates."

Boy, that's some good writing right there. You can read an excerpt of "Not Afraid of Life" at the ABC News website. The book hits shelves Tuesday (June 21).
