And you thought the Hemsworth brothers were hot.
It all started because of an innocent Instagram post from the youngest brother during a Malibu hike with his parents and pups. "Climbed a mountain with the oldies this morning and came across a rattlesnake after telling my brother there were no rattlesnakes in this area," Liam wrote.
What the actor didn't acknowledge that everyone else saw was his dad's insane muscles.
No dad bod for the Hemsworth patriarch! He's in amazing shape displaying his bulging biceps and ripped stomach, which didn't go unnoticed by Liam's 11 million followers.
Don't forget, he made Thor.
