Chris Hemsworth celebrates his twins' second birthday

Actor Chris 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 March 18 when the boys officially turned two.

"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.
