Elsa Pataky dresses up as a blood-soaked nurse for Halloween while trick-or-treating barefoot with her brother-in-law Luke Hemsworth

Elsa Pataky embraced the Halloween spirit as she went trick-or-treating with her children in Byron Bay on Tuesday.

The 47-year-old Spanish-born actress was seen walking barefoot through the streets, wearing a blood-soaked nurse’s outfit.

Elsa donned a white mini dress with bloody splatters, a wig and a headpiece.

Meanwhile, Luke Hemsworth, her husband Chris’ brother, wore a Beetlejuice-inspired outfit that consisted of black and white stripped clothes and a green colored wig.

Chris and Elsa’s twin sons, Sasha and Tristan, were dressed in Ninja Turtles outfits.

They were joined by Luke’s family and close friends, who were all dressed up for the occasion.

Nowhere to be seen was Elsa’s husband Chris Hemsworth, 40, and the pair recently spent some time apart as they took separate holidays last month.

Marvel star Chris took the couple’s daughter India to Iceland, while Elsa took her twin brothers Tristan and Sasha, nine, on an adventure trip to Tokyo, Japan.

Chris and Elsa met in early 2010 and married in December of that year.

The family of five live in Byron Bay, on the NSW north coast, in a mega-mansion estimated to be worth $30 million, after moving from Los Angeles in 2014.

They spent years renovating their home, which sits on 4.2 hectares of land, with the help of Sydney-based MCK Architects, but the development was met with some resistance from locals, who likened it to a multi-storey car park or shopping centre.

Elsa recently said that patience, communication and understanding were the key to her successful marriage.

“You have to put a lot of work into marriage; “I don’t think every couple is perfect,” she said.

‘It takes patience, understanding, talking a lot, getting to know the other person, getting to know yourself and knowing what you are doing wrong. It’s about not letting your pride get in the way.”

Elsa also said it was important for her and Chris to spend time together as a couple without the kids.
