Miley Cyrus and boyfriend, Justin Gaston, living together?

According to STAR, "Hannah Montana" star Miley Cyrus and and her new 20-year-old boyfriend, Justin Gaston, are already living together.

Justin has his own apartment but has spent most nights in the Billy Ray Cyrus and Tish's California house.

“Justin is the guy Miley’s parents see her settling down with a few years down the line,” their snitch says. “He’s handsome, talented, clean-living, goes to church and knows his Bible -- a real catch.”

"He actually reminds me a lot of myself when I was 20 years old and I was living and searching for the dream," Billy Ray told Access Hollywood. "He's got a great heart and soul, and a lot of determination. I think that's the true measure of a man, is when you measure his heart."

The insider adds: “Billy Ray wasn’t born yesterday. He figures the safest path to take is to keep Miley and Justin on a short leash-and under the same roof.”
