Kissing Miley Cyrus: Liam Hemsworth Tells All

Miley Cyrus' first kiss with Liam Hemsworth wasn't the most tender of moments. It unfolded on camera – in front of an entire crew – during The Last Song.

Not that the Australian actor was disappointed when it happened.

"We turned up on set the very first day and originally it was just a scene where we were running through the water and splashing and having fun," he said.

All in her first movie acting gig. No wonder Miley's quitting music.

"And halfway through the scene, the director yelled 'Kiss!' And we got thrown into a kiss on the boat," he recalled on Ryan Seacrest's KISS-FM radio show.

While it was "hard not to get close" to his costar while filming in Tybee Island, Ga., "It was good, 'cause, you know, [you] get the first one out of the way."

"We were filming together every day, and hanging out every day," Liam added. "We really didn’t have any other friends down there, so we just hung with each other."

It also helped that Miley Cyrus' mother, Tish, whom Liam Hemsworth described as "the boss," gave a stamp of approval on the budding relationship early. Her dad?

Well, Billy Ray another pressing question for Hemsworth, which Seacrest relayed: "How serious is it gonna get?" Hemsworth's reply was simply: "It's pretty serious."

Gulp.

Recently, the couple stepped out for the first time as a couple on the red carpet for the Los Angeles premiere of The Last Song, which hits theaters on Wednesday.

Hemsworth said he's still getting used to the media spotlight – not to mention attention that comes with a high-profile girlfriend: "It's all very new to me," he said.

New and hot. Don't you think these two make a great couple? Much as we are often critical of Miley, it seems like Liam's been a good, grounding influence on her.
