Nicole Kidman paid tribute to her late mother Janelle and the daughters she shares with husband Keith Urban – Sunday Rose and Faith Margaret – when she shared a touching Mother’s Day post to Instagram on Sunday.

But there was a very notable absence from the Hollywood star’s upload. 

Nicole did not mention the two adopted children she shares with Tom Cruise – Bella, 32, and Connor, 30.

The Big Little Lies star shared two pictures in the post, including one of the actress posing with her mother and daughters in front of Uluru.

The second photo showed Janelle walking with her two granddaughters on a track near the Indigenous sacred site.

‘My mother and my daughters in Uluru, beautiful memories… Always Happy Mother’s Day,’ Nicole wrote in the caption.

It has been widely reported that Bella and Connor have long been estranged from Nicole following her divorce from their father Tom. 

Reports emerged in December suggesting Nicole was determined to reconnect with the pair following the devastation of losing her mother.

‘Losing her mum has made Nicole not want to waste any more time,’ a family friend told New Idea magazine last year.

‘It hurt Janelle that she and husband Antony were estranged from [Bella and Connor].’

Nicole and Tom, 62, adopted Bella and Connor in the early 90s but following their split in 2001 the two children sided with their father, and have not been publicly seen with their mother since 2007.

‘They were their first two grandchildren and were once very close. It was a deep regret that they were unable to see her in person before she died,’ added the source.

They said the regret was ‘fuelling her need for a proper reconciliation’.

Nicole’s beloved mother Janelle died in September last year, just hours before the movie star was awarded Best Actress for her role in Babygirl on the final day of Venice Film Festival.

‘Today I arrived in Venice to find out shortly after, that my beautiful, brave mother has just passed,’ Nicole revealed in a statement read by director Halina Reijn upon her win.

‘I am in shock and I have to go to my family, but this award is for her, she shaped me, guided and made me.

‘I am beyond grateful I get to say her name to all of you through Halina, the collision of life and art is heart-breaking, and my heart is broken. We love you all.’
