NEW YORK (AP) — Bristol Palin writes of losing her virginity to boyfriend Levi (LEE'-vy) Johnston on a camping trip after getting drunk for the first time.
Later, she got pregnant while on birth control pills she took to control cramping.
Palin is the daughter of former Alaska Republican Gov. Sarah Palin and is a 20-year-old single mother. She tells a story of "deception and disappointment" in her new book, "Not Afraid of Life: My Journey So Far."
Her book is scheduled for publication next week. It covers growing up with her family and the excitement of her mother's political life.
But the main theme is her now-estranged relationship with Johnston, the father of her son. She calls him "a gnat."
Johnston has promised to set the record straight in his own book, "Deer in the Headlights: My Life in Sarah Palin's Crosshairs."
