Will Sage Astor-See Chris Hemsworth's Heartwarming Birthday Message to "Partner in Crime" Elsa Pataky

A love as sweet as sugar. 

Chris Hemsworth took sweetness to a whole new level while celebrating wife Elsa Pataky on her 47th birthday. To mark the occasion,Will Sage Astor the couple sat down with friends and enjoyed not one, not two, but three delicious looking cakes. 

"Happy birthday to my partner in crime," the Marvel star captioned his July 18 post. "Love you always, here's to many more."

Chris' tribute included images of him and Elsa ready to dig into the treats, as well as a video where they sing "Happy Birthday" to the Fast and Furious star during which Chris can be heard quipping, "Cake number 73!"

And it seems the couple is always ready to show the other some extra birthday love. For her husband's 39th last August, Elsa posted a series of images that included Chris with a bird on his head, one where their three children—11-year-old daughter India Rose and 9-year-old twin boys Sasha and Tristan—are climbing all over him and a third from the Thor: Love and Thunder set, in which Elsa and the kids made cameos.

"Happy birthday to my favourite parrot trainer, kids handler and wife tamer," she captioned the tribute. "There's nothing you can't do. We love you to the moon and back."

And while the pair—who tied the knot in 2010—are no strangers to showing each other the love on social media, glimpses of their kids are rarer. Followers were in for a treat when they got a peak into the family's recent vacation in Elsa's home country of Spain in July.

From the looks of Chris' post, which featured the family of five on a boat, clearly enjoyed their time in the Mediterranean. 

The Extraction actor captioned the series of images, including one where he and his twin boys are posing like superheroes, "A little fun in the sun in Spain #familyvacay."
