EXCLUSIVE: Sarah Palin fires back at Dakota Meyer paternity drama

Two weeks after Bristol Palin gave birth to daughter Sailor Grace, her ex-fiancé, Dakota Meyer, is claiming to be the biological father and seeking joint custody.

Bristol's mother, former vice-presidential candidate and Alaska Governor Sarah Palin, spoke to ET exclusively about Meyer's claims.

"For many months we have been trying to reach out to Dakota Myers [sic] and he has wanted nothing to do with either Bristol's pregnancy or the baby," Palin told ET.

Meyer filed legal documents alleging that he's Sailor Grace's father, and is seeking joint custody of the newborn girl, as well as child support, TMZ reports.
