Could the father-son duo be any cuter?

The 32-year-old actor made his Instagram debut Monday with a selfie of him sporting a FDNY hat and posing in front of a giant snake that made its way onto his lawn.

"Hangin' with the locals in my backyard… the real Jurassic Park," he wrote.

Looks like his account will be a mix of charming and funny posts. Taking after his younger brother, Liam, perhaps?

Whether Hemsworth is using babies or actual weights in the gym, his time spent working out has been paying off. He proved that last month when he showed off his chiseled abs while surfing in Byron Bay in New South Wales, Australia.
