Liam Hemsworth is the spitting image of his dad in this old photo

Good genes.

Liam Hemsworth shared an image on Instagram to pay tribute to his mother on her birthday. He shared a photo of his parent's wedding day as they cut the cake saying:

"Happy birthday to my beautiful mum! Not sure what dads doin (sic) here but I Love u mum you’re the best! Dad you’re an idiot."

While everyone was swooning over his adorable post, they've also pointed out one thing - that Liam is the head off his dad.

"I know that's your dad but he looks exactly like you but just with a lot of beard hair." "You look exactly like your father and Chris like your mother." "Oh my goodness don't you look just like him."
