Cover your eyes, Miley: Shirtless flirt Liam Hemsworth passionately kisses co-star Teresa Palmer in new film stills

It's all in the name of good, honest acting, of course.
But Miely Cyrus might want to look away now - because her hunky fiance Liam Hemsworth is seen here getting to grips with his stunning co-star Teresa Palmer in newly-released stills from their film, Love And Honor.
The 22-year-old Australian actor goes shirtless to share a steamy clinch with fellow Aussie star Palmer, 26, who dates Canadian actor Scott Speedman.

The movie, which is due for release sometime this year, is set during the Vietnam War and tells the true story of Michigan soldier Dalton Joiner (played by Austin Stowell) who secretly returns home from war to win his girlfriend back after being dumped.
Hemsworth plays the role of his best friend, Mickey Wright, and accompanies him on their covert mission.
Aimee Teegarden plays Stowell's onscreen love interest - while Palmer falls for the charms of Hemsworth's character.

And judging by these stills, there certainly seems to be a lot of chemistry between them.
The most racy shot shows the Hunger Games actor shirtless as Palmer kisses him while wearing a lacy bra.
In another image they are seen lying outside on a blanket; Liam is shirtless again and embraces a scantily-clad Palmer in her underwear.
The romantic drama, previously titled AWOL, was shot last summer in and around Ann Arbor in Michigan.
