‘Miley Cyrus‘ musician father Billy Ray Cyrus reportedly doesn’t permit his daughter to dump her current lover Justin Gaston. A source tells National Enquirer that the 47-year-old country singer tells Miley she is “behaving immaturely and that she’ll regret dumping Justin.”

Billy Ray Cyrus first introduced Justin Gaston to Miley Cyrus on the set of her TV series “Hannah Montana”. Since then, he began loving the 20-year-old underwear model as he let him move into his house in Toluca Lake, California. However, Justin was said refusing his good deed, as the source discloses, “Lately he’s been spending more nights at his apartment.”

Recently, Miley reportedly expected to end her romance with Justin. “Miley thinks her career is at a tipping point, where she’s transitioning from kid stuff to more mature movies and music, and she doesn’t want to be tied down with Justin. She has a nagging feeling that Justin is trying to ride her coattails to success and she resents that,” the source continues. “It’s finally dawning on her that she’s young, rich and famous – and she can have any guy she’s interested in.”

Additionally, the Disney star was reported having a crush on British actor Gregg Sulkin. “Miley thinks Gregg is just awesome. She’s taking it one step at a time but they both would love to make a proper go of it,” a source told Daily Star. “The thing with Justin wasn’t that serious – but with Gregg it could be for keeps.”
