The heartbreaking reason Nicole Kidman is determined to reconcile with her two older children, following the shock death of her mother Janelle in September, has been revealed.

The Oscar-winning star, 57, is reportedly devastated her late mother never got a chance to reconnect with the two adopted children she shares with ex-husband Tom Cruise.

‘Losing her mum has made Nicole not want to waste any more time. It hurt Janelle that she and husband Antony were estranged from [Isabella and Connor],’ a family friend told New Idea magazine.

Kidman and Cruise adopted Isabella, 31, and Connor, 29, 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.’

Kidman has four children: Bella and Connor with Cruise, and daughters Sunday, 16, and Faith, 13, with her current husband Keith Urban.

Her beloved mother Janelle died in September, just hours before Nicole 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.’

One week later, Nicole broke her silence and made a heart-wrenching Instagram statement alongside several never-before-seen photos of the matriarch.

In her post, the Perfect Couple star thanked her millions of fans and supporters for expressing their condolences during their time of grieving.

‘My sister and I along with our family want to thank you for the outpouring of love and kindness we have felt this week,’ Nicole wrote in the joint statement.

‘Every message we have received from those who loved and admired our Mother has meant more to us than we will ever be able to express. Thank you from our whole family for respecting our privacy.’

Nicole has long had an incredibly close relationship with her beloved mother Janelle and often spoke about her support and influence on her career over the years.

She was born in Hawaii and raised in Sydney by Janelle and her psychologist father Antony, who died in September 2014.

After spending time in the United States, the Moulin Rouge star and her younger sister Antonia spent much of their childhood in Sydney.

Nicole pursued her passion for acting when she was a teenager and was supported by both of her parents as she soared to global fame.

They both remained closely involved with her career over the years, with Nicole often admitting she would go to her mother for advice.

Nicole had an equally close relationship with her father Antony and was left devastated when he died of a heart attack in September 2014 aged 75.

The Oscar-winning actress previously revealed the ‘sudden’ death of her father, as well as a string of other losses, had deeply affected her.
