Sarah Palin's dad slams granddaughter's ex-fiancé over poor parenting

New York, April 15 (ANI): Sarah Palin's father, Chuck Heath, has lashed out at Levi Johnston, the father of his great-grandchild, for not contributing enough money for the well being of his infant son.

Heath accused 18-year-old Johnston, who has a four-month-old son with Alaska Governor's unwed teen daughter Bristol, for capitalising on interviews.

He told US Weekly magazine that he hopes Johnston would "take some of this money he's making and buy some diapers with it," reports the New York Daily News.

Johnston had revealed his side of the story on "The Tyra Banks Show" and CBS' "The Early Show" and reps from both the shows confirmed he was not paid for the appearance.

Bristol's former fiancé had alleged that he was being prevented from being with his son, and also claimed that the former Republican vice-presidential candidate knew of his sexual relations with his daughter. (ANI)
