Chris Hemsworth hugs his twin boys in adorable birthday photo

BYRON BAY, Australia, March 22 (UPI) -- Chris Hemsworth is melting hearts on social media after his wife Elsa Pataky shared an adorable photo of the actor hugging his twin boys Tristan and Sasha on their birthday.

"Happy birthday my little boys," the model and actress captioned the photo on Instagram Monday after writing the same message in Spanish.

"There's nothing that makes me happier in life, than being a mum and watch you growing up everyday! #mum #boysbirthday #bestlove #party #already2 #loveyou," she continued.

Hemsworth and Pataky, who married in 2010, spent the weekend celebrating Tristan and Sasha's second birthday in their new residence in Australia. The couple are also parents to 3-year-old daughter, India.

In January, Hemsworth and Pataky discussed moving back to Australia from Los Angeles with the Avengers star stating "It wasn't a hard decision to move back to Australia because this part of the world is such a special place. This is the place I want my kids to grow up -- that's the world I want them to be part of. I'm really looking forward to launching this new campaign in New York and sharing with the rest of the world just how amazing this country really is."

Hemsworth will next be seen in the upcoming Ghostbusters revival out in theaters July 15.
