The Australian actor, who rose to fame as Jennifer Lawrence's manly, roguish, bicep-blessed hunting companion in The Hunger Games, showed off his well-defined muscles even while outfitted in loose tunic-vest ensembles. Not only does Thor's little brother fill out his clothes amazingly well, but he also possesses icy blue eyes (which he can morph into a sexy squint instantly) and a face full of scruff. And according to the actor's betrothed, he's even hotter off-screen ... in a pool and shirtless. A gushing Miley Cyrus shared this tidbit with Cosmopolitan,"The other day, I turned on the pool heater and it was steaming, and he walked outside and took off his clothes and jumped in the pool. I was like, 'I'm gonna faint — the hottest guy of my life is in a steaming pool. This looks like a Playgirl shoot.'" She then proceeded to take a photo of him and make it the background of her phone. But she didn't, we shall note, send it our way yet.
