Miley Cyrus has finally moved on from longtime love Justin Gaston. After a brief fling early in the summer with old flame Nick Jonas, she’s officially dating her The Last Song co-star Liam Hemsworth.

The teens met on the set of their Nicholas Sparks film and spent a romantic summer jet-skiing and making out on-set on Tybee Island in Georgia, and now they’re spending quality time together in Los Angeles.

Last week during Miley’s concert with her brother Trace’s band, Metro Station, Miley, 16, rocked an audience that included Liam, 19, who had a specially reserved seat at the side of the stage – the spot where family and loved ones get to hang out!

One spy tells me, “Liam was smiling as he watched Miley perform. He was enjoying himself and getting into the excitement right along with her screaming fans. After the show, they met up at Katsuya for the afterparty. They arrived separately but spent the night together and left together.”

“Miley is a girl that likes having a boyfriend and she is having lots of fun flirting with Liam. They’re cute and still fairly innocent about their relationship. She has asked him to stay as quiet as possible about it to keep the frenzy to a minimum, but she’s happy and enjoying having a cute boy to send time with. They go on dates to the movies, but stay hidden away at home most of the time so they can have some privacy.”
