Levi Johnston, Bristol Palin’s ex and father of her child, is writing a tell-all about his relationship with the whole Palin family, he announced Monday. The book, Deer in the Headlights: My Life in Sarah Palin’s Crosshairs, will be released in the fall by Touchstone Publishing. “I want to tell the truth about my close relationship with the Palins,” Johnston said in a statement. Johnston famously appeared on stage with the Palin family at the Republican National Convention in August 2008 before breaking up with Bristol and subsequently falling out with the family. Since then, Johnston has dabbled with celebrity status—he appeared as a Playgirl nude model—and has toyed with running for Wasilla mayor.
