Chris Hemsworth has proved he really deserves his Sexiest Man Alive title.

The hunky actor is quite possibly the most ripped human being on the planet.

The Aussie star showed off his schermazing bod in a new trailer for Vacation – a comedy film about a family holiday.

The blonde Thor star parades around in a pair of very tight grey boxers in the clip, and poses in numerous seductive positions, showing off his six-pack from all angles.

The star also shows off a bulge in his pants in the clip – which we presume was a prosthetic used to add comedy value.

Chris plays Stone Crandall in the new blockbuster – the husband of main character Rusty Griswold’s (Ed Helms) sister.

He hosts the family in his home for a night, and is showing them the facilities in their room when he makes his debut in his pants.

“He totally just came in here to show off his six pack,” Rusty declares as Chris exits the scene.

Well, we’re not complaining…

The star was recently named the Sexiest Man Alive by People magazine – and says his wife laughed when he told her.

“She thinks it’s as funny as I did!” he said.

“We had a good laugh about it. It’s ridiculous but I’ll take it while I can because this may be my peak.

“I might start to decline and fall apart now. The grey hairs are starting to show already.”

Somehow, we really doubt that…
