From the beefy arms to the perfect amount of scruff, we can see why Miley Cyrus has this man locked down! Well, for now...

Liam Hemsworth waved to fans and photographers outside of Jimmy Kimmel Live! on Monday afternoon, and even in a simple black tee, the 23-year-old Aussie actor was looking smokin' hot.

But don't expect his Twitter feed to be heating up anytime soon, because at the Los Angeles premiere of his new flick Paranoia, Liam opened up about his recent decision to join the social media site and how he's keeping his feed strictly professional.

"On Twitter I don't share anything personal," Liam told E! News. "I try to keep as much of my personal life to myself, and I don't feel the need to go out and show the world what's happening in my life every second ... I think it's a good chance to connect with fans in a different way and give fans an inside look on films that you do. But it's very new to me and it scares the hell out of me."

"No shirtless selfies," he added with a laugh. Boo!
