Chris Hemsworth goes barefoot with his sons as he returns to Byron Bay – after fans expressed concerns over marriage to Elsa Pataky

Chris Hemsworth is back home in Bryon Bay after a busy few months flying around the world.

The Australian superstar was flanked by his two sons, Tristan and Sasha, as he went for a barefoot walk in the NSW coastal town where he lives with his family.

The 40-year-old looked relaxed as he walked around in an olive green shirt and camouflage trousers.

He completed his casual look with sunglasses and a watch, while ditching the shoes.

It comes next fans were concerned about Chris' status and his wife Elsa Pataki's relationship.

They are one of Hollywood's longest-lasting couples and have been married for more than 10 years.

But the genetically blessed duo has spent a significant amount of time vacationing separately in recent months, leaving fans wondering if all is well in paradise.

Because the fans expressed their concerns, Chris shared a photo of himself and Elsa on Instagram on Sunday, where the pair are seen soaking up the sun aboard a boat.

The banter started after Elsa and the couple's children set up the family Christmas tree at their Byron Bay mansion without Chris.

“I haven't seen you and Chris together in a while. I hope all is well,” a follower commented under the photos the Spanish star posted of the Hemsworth clan decorating the house.

“Where's Chris?” wrote another concerned fan, as one noted that the pair have taken fewer photos together than usual.

Ny Breaking Australia has reached out for comment.

In October, Elsa, 47, flew to Japan with twin sons Tristan and Sasha, nine, without her husband.

Meanwhile, Chris took their daughter India, 11, on a father-daughter trip to Iceland.

Both parents documented their separate vacations on social media at the time, leaving many confused as to why the mega-rich couple didn't join in on their vacation plans.

In November, the couple went on separate trips again.

Elsa traveled back to her native Spain to attend The Woman Awards, where she braved a storm in a daring, backless dress.

Her husband was noticeably absent and instead decided to travel to Abu Dhabi for a family getaway with his genetically blessed brothers Liam and Luke, their partners Gabrielle and Samantha and the siblings' famous parents, Craig and Leonie.

Chris' twin sons Tristan and Sasha, nine, also joined their dad on the whirlwind trip.

It is unclear whether India accompanied her mother or father on their respective journeys.

The action star was also in the UAE capital to attend the F1 Grand Prix with his famous brothers and male friends.

Earlier this month, Chris headed to Brazil to promote his new film Furiosa with co-star Anya-Taylor Joy.

His three children stayed with their mother in Australia, who shared a video of her cycling on the beach with the children on Thursday morning.

Chris and Elsa spent time together in their hometown of Byron Bay in October.

Elsa posted a photo of the couple on Oct. 12 taking their kids for a ride on a dirt bike on a farm.

Chris and Elsa got married over the Christmas holidays in 2010.

The couple live in a $30 million mansion in Broken Head, near Byron Bay, after moving from Los Angeles to Australia nine years ago.
