(AP Photo/Paul Sancya, File) (Newser) – There's no love lost between the Johnston and Palin clans, and Levi's new tell-all memoir is set to keep the feud going. In Deer In the Headlights, to be released later this month, Johnston claims that Bristol became pregnant with his child to get even with her mother for Sarah's pregnancy with Trig, reports the New York Daily News. He says Bristol, then 17, believed that she, not her politician mother, should be having babies. Johnston—who says he was "too dumb" to use birth control—claims that Sarah offered to adopt the baby to "avoid a scandal," but he and Bristol turned her down. He scoffs at Bristol's claim that she lost her virginity to him after drinking wine coolers on a camping trip. The couple didn't go camping together until after they had become sexually active, he says, so if Bristol lost her virginity on a camping trip, Levi quips he "wasn't there."
