Levi Johnston on Sarah Palin: She Doesn’t Intimidate Me

In an all-new interview with ET special correspondent Diane Dimond -- Levi Johnston, the father of Sarah Palin's grandson, opens up about his efforts to see his son Tripp and how he feels the Palins don't want him to be a part of his son's life.

"I don't know -- They just don’t want me in his life," Levi says.  He says he believes this based on things his son's mother Bristol has said to him, but believes it is the former GOP vice presidential candidate who is "feeding her something." 

As for Sarah's upcoming book that may or may not discuss Levi, the 19-year-old tells us, "[Sarah] doesn't bother me ... Just because she ran for vice president and was governor of Alaska doesn't intimidate me."
