‘Hannah oontana’ star Miley Cyrus confesses her country musician dad, Billy Ray, isn’t great on giving relationship advice.”Dad’s useless when I break up with a boyfriend,” she laughs. “He just says, ‘There’s plenty more fish in the sea.’ once he actually said, ‘He wasn’t that great-looking anyway’. He’s a harsh man to my boyfriends but only after we’ve broken up. He’s pretty cool with them when they’re with me.”
