Levi Johnston is the thorn in Sarah Palin’s side that just will not go away. Johnston recently posed nude for Playgirl magazine but he is clearly not done baring all. He is writing a book giving an inside view of the famous Palin family. Johnston had a relationship with Sarah Palin’s daughter Bristol Palin that produced a son, Tripp. His book is called Deer in the Headlights: My life in Sarah Palin’s Crosshairs and it will be released this fall by Touchstone Publishing. Johnston says he wants to tell the truth about his close relationship with the Palins and his perplexing fall from grace.
