Miley Cyrus appears to have traded Nick Jonas in for a tall, dark and handsome model who goes by the name of Justin Gaston.

It seems that 15-year-old new grown up image is matched by a new grown-up taste in men.

So it's goodbye baby-faced Nick and hello 20-year-old Justin, a country singer-come model who has posed for labels such as Guess and Kenneth Cole.

The two met on Miley's father Billy Ray's show Nashville Star and have apparently remained 'good friends' ever since.

People quotes a source close to Miley as saying, “They've been spending a lot of time together while he's in town."

Justin visited Disney’s Concert for Hope on Sunday to see Miley perform.

Just good friends? We're not so sure.

See Miley suddenly all grown up here.
