Nicole Kidman and her husband Keith Urban are said to be considering a move back to their native Australia following a very difficult year.

The actress, 57, recently suffered a personal tragedy after the death of her beloved mother Janelle in September, which saw her return to Sydney for the funeral.

Amid the very difficult time, Nicole had a very busy schedule jetting around America promoting her latest movies and filming yet another project.

Her loved ones are said to be worried about Nicole suffering from a ‘burnout’ and the Big Little Lies star and Keith are now reportedly considering returning to Australia.  

‘Nicole and Keith have had their worst year ever, they’ve barely spent any time together and she’s been on her own throughout some of her most distressing times,’ a source told Woman’s Day.

‘The big worry on everyone’s minds is, how much more of this can she take?’

Country singer Keith, 57, is said to be considering stepping back from touring to support Nicole after his 10-date Las Vegas residency comes to an end in February.

Daily Mail Australia has contacted Nicole’s representatives for comment.

Nicole recently united in grief with her family – including her younger sister Antonia – back in Sydney as they all attended her mother Janelle’s funeral.

Janelle died at the age of 84 last month – just hours before Nicole was awarded the Best Actress gong for her role in Babygirl at the Venice Film Festival.

Nicole was supported by Keith and their two daughters Sunday Rose, 16, and Faith Margaret, 14, before they all flew back to Los Angeles together.

Nicole and Keith own a sprawling 20-room Nashville mansion, which cost them $4.89million, as well as a $6.77million home in Beverly Hills and $13.53million designer duplex in Chelsea, New York.

They also still own properties Down Under, including a $6.5million farmhouse in the Southern Highlands and two penthouses in Milson’s Point in Sydney, which they lease out.

Nicole is currently in the US filming an upcoming six-part crime series Scarpetta, and has been spotted at an array of red carpets promoting her latest release, Babygirl.

However, her busy schedule is said to have sparked concern she could suffer a ‘burnout’ from overloading herself with the releases and their full-on press tours.

A source recently claimed that people are particularly concerned for Nicole as she is currently also dealing with her grief following Janelle’s death. 

‘Nicole is still looking as amazing as always but she’s been through so much, and she seems to be dealing with her grief by throwing herself into work,’ a source told Woman’s Day magazine.

‘There are times when she sleeps on a plane more than a bed. Everyone’s worried about her.’

Amid her busy year, Nicole has already starred in Netflix’s age gap rom com A Family Affair, while her other steamy romance Babygirl is slated for release in December.

Nicole has also starred in Netflix’s thriller series A Perfect Couple and series two of Special Ops: Lioness as she has packed her schedule full in recent months.

Nicole recently reflected on her jam-packed working life and told how she finds it difficult to take a break away from the cameras and simply take time for herself. 

‘It’s very hard for me to go, ”Okay, I’m just going to take care of myself,” because I’m so much about taking care of other people,’  she told Variety. 

‘I’m thinking, ”I can create more work for people. I can create jobs for people.” And also, I love it. I have the pᴀssion.

‘I’ve just got to take care of my body. I wish I had superpowers because I would love to be everywhere.’
