Miley and Her Man Get Serious

Miley Cyrus is so excited about her new man, underwear model Justin Gaston, that she can’t bear for them to be apart!

“Justin and Miley are constantly texting each other,” a friend of Justin tells OK!. “They text things like, ‘I miss you so much,’ and ‘I can’t wait to see you.’ It’s all very cute and lovey-dovey. Justin also thinks highly of Miley’s opinion — he’s thinking about getting a tattoo and was asking her for ideas."

Justin, 20, who attended a Sept. 13 church service on his first date with Miley, 15, joined the Cyrus clan at Universal CityWalk on Sept. 21 for another family day out.

Meanwhile, he’s making sure he’s a permanent fixture in L.A. – as well as Miley’s life – by moving into a friend’s pad.

“He brought all his clothes from Louisiana,” the pal says. “He also said to expect to see Miley coming by the house more often.”
