Nicole Kidman reveals the last four words her late mother Janelle said to her before she died

Nicole Kidman has revealed the last words her late mother Janelle said to her before her death in September.

The Australian actress, 57, opened up about her mum as she appeared on CBS Sunday Morning in the US over the weekend.

'The final words my mama said to me, I was gonna get on a plane, and she said "Maybe wait a minute, because you just need to take care of yourself, Nicky,"' Nicole said.

The Hollywood actress said she has since taken her mother's advice to heart. 

'I'm doing that more, and I say that to other people in the world. Particularly women. I think we tend not to care of ourselves. We take care of everybody else but the last person is here,' she said. 

The Babygirl star also revealed her mother Janelle wasn't the only woman in Nicole's family with sage advice. 

'My grandmother left me with "Be happy" and my mother said "Take care of yourself."'

It comes after reports Nicole and Keith are considering a move back to their native Australia following a very difficult year. 

After the death of her beloved mother in September, which saw her return to Sydney for the funeral, Nicole had a very busy schedule jetting around America promoting her latest movies and filming yet another project.

The star's loved ones are said to be worried about Nicole suffering from a 'burnout' and Nicole 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 in September - 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, at her funeral.

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.
