Miley Cyrus and her model boyfriend Justin Gaston, have been playing house since he moved from Louisiana. A family friend tells Star that Miley's parent, Billy Ray and Trish resisted the idea at first, but have come to the conclusion that, " If Miley is going to date someone, it better if they can keep an eye on them." The source also said, that Justin even has some influence on the house hold. " He convinced the Cyruses to build a $60,000 recording studio so they can record music together." Would you let your 16 year old daughter have a live in boyfriend?
