Chris Hemsworth Demonstrates 'How Babies Are Made in Australia' in Valentine's Day Video with Elsa Pataky

The couple, who have been together since 2010, are the parents of three children

Chris Hemsworth is letting fans in on a cheeky secret.

On Wednesday, the Avengers star, 40, posted a slow-motion video featuring his wife, Elsa Pataky, 47, swimming underwater. Hemsworth, an Australia native, then swims up from behind and grabs her in an intimate embrace while Enya’s 2000 hit “Only Time” plays.

“Happy Valentine’s Day,” Hemsworth wrote with the video. “This year I thought I’d share with you how babies are made in Australia. It’s both a game of passion, love and intense sportsmanship where [everyone’s] a winner. ❤️💋 @elsapataky"

Hemsworth and Pataky — who have been married since 2010, the same year they met — frequently post photos together on social media.

In January, the actress and model shared images from a family vacation to Asia featuring their daughter India Rose, 11, and 9-year-old twins Tristan and Sasha.

“Last week of our summer summer holidays!! Japan is always fun,” she wrote.

Earlier that month, they took a New Year’s Eve ski trip and were joined by Matt Damon.

In 2022, Pataky talked to PEOPLE about how Hemsworth helped her prep for her Netflix action movie Interceptor, on which her husband was a producer. (He also had a small cameo.)

“He was there to just [offer] all kinds of advice. Of course, he’s a professional action-movie star. So it was great to have him holding my hand,” she said.

During some of her fight scenes, Hemsworth weighed in and offered his wife tips.

“He knows exactly how to throw a punch,” she said, adding that she sometimes bristled at his suggestions. “We’re very competitive. [I was like] ‘Okay, I know what I’m doing.’ But in this case, he knows more.”

Hemsworth told Elle in 2015 that they hit it off from the get-go after his agent set them up. “From the first time we met, we just made sense. She’s fun. She’s outgoing, and she has a sense of humor and a passionate attitude toward life, which is nice to try to keep up with,” he said.

He added that Pataky and their children help keep his massive fame in perspective.

“I can say that [my family] has certainly kept my feet planted firmly on the ground — I’ve been able to bypass a whole lot of garbage, traps that I could have fallen into,” he told the outlet. “I had a taste of it when I was younger and on a TV show in Australia, and it wasn’t of great interest to me even then.”
