Chris Hemsworth may rule the Marvel world as Thor, but he didn't need to wield his hammer on his kids' birthday.

Hemsworth's wife, Elsa Pataky, shared a precious photo of her husband giving their twin boys, Tristan and Sasha, a massive bear hug. She posted the photo to Instagram on Monday, though the boys officially turned two on March 18.

"Happy birthday my little boys," the 39-year-old actress captioned the snap, which she also wrote in Spanish. "There's nothing that makes me happier in life, than being a mum and watch you growing up everyday!"

She added plenty of both perfect and delightful hashtags as well, including #mum, #boysbirthday, #bestlove, #party, #already2, and #loveyou.

While Hemsworth, 32, did not share the photo on any of his social media accounts, he did wish a very happy birthday to a different party -- Twitter! The social media site turned 10 on Monday.
