Fifteen-year-old singing superstar Miley Cyrus and her 20-year-old boyfriend are both living in her father’s home, said The National Enquirer. Billy Ray Cyrus wants to keep model Justin Gaston “on a short leash,” a source told the tabloid, but he also wants to let his daughter know he approves of the relationship. “Justin is the guy Miley’s parents see her settling down with,” said the source. “He’s handsome, talented, clean-living, goes to church, and knows his Bible.”
