"It's my job to love them." Inside Nicole Kidman's relationship with her two oldest children.

In 2018, Nicole Kidman stepped on stage at the Golden Globes to receive an accolade for her role in Big Little Lies.

Accepting the award in front of her husband Keith Urban, the actress thanked her two young daughters – Sunday Rose and Faith Margaret.

“Sunny, Faith, I love you. I’m bringing this home to you babies,” she said.

At the time, the 51-year-old’s acceptance speech led to a flurry of questions from fans and the media alike.

While Kidman had thanked her two youngest children in her speech, many questioned why she had failed to mention her two oldest children – 26-year-old Isabella and 24-year-old Connor – who she shares with her ex-husband Tom Cruise.

Now, amid rumours that Kidman wasn’t invited to Connor’s upcoming wedding to his partner Silvia Zanchi, the actress’ relationship with her adoptive children is back in the spotlight once again.

The rumours of a rift between Nicole Kidman and her two eldest children first began when she separated from her former husband Tom Cruise in 2001.

At the time, their kids – who had been raised in the Church of Scientology – chose to stay with their father.

In the years following their separation, it’s been claimed on multiple occasions that the Church of Scientology caused a significant fracture in Kidman’s relationship with her adopted children.

In Steve Cannane’s book Fair Game: The Incredible Untold Story of Scientology in Australia, it’s alleged that after Tom Cruise and Nicole Kidman’s relationship ended, the Church of Scientology tried to turn Nicole’s children against her.

Actress Leah Remini, who was previously involved in Scientology, backed up the claims, alleging that Isabelle and Connor consider their mother a "suppressive person" - a person who has publicly renounced their faith and is no longer allowed to be in contact with other members of the church.

In her memoir, Remini recalled being in the car with Isabella and Connor, and asking if they had seen their mother recently.

"Not if I have a choice," Isabella answered, according to the book. "Our mum is a f*cking SP [suppressive person]."

But while Kidman's relationship with her two oldest children might not be entirely conventional, according to the actress, the reports surrounding an alleged rift between her and her children are completely false.

"I’m very private about all that. I have to protect all those relationships. I know 150 per cent that I would give up my life for my children because it’s what my purpose is," Kidman told Who magazine late last year.

When probed about her children's relationship with Scientology during the same interview, Kidman remained diplomatic in her response.

"They are able to make their own decisions. They have made choices to be Scientologists and as a mother, it’s my job to love them," she told the magazine.

"And I am an example of that tolerance and that’s what I believe – that no matter what your child does, the child has love and the child has to know there is available love and I’m open here," she added.

"I think that’s so important because if that is taken away from a child, to sever that in any child, in any relationship, in any family – I believe it’s wrong. So that’s our job as a parent, to always offer unconditional love.”

In a recent Vanity Fair profile, Kidman spoke briefly about her two older children.

“Bella lives just outside London. You know, she really feels more English. We lived there for Eyes Wide Shut, Mission Impossible, and The Portrait of a Lady,” she said.

“They both had English accents when they were little,” she added.

Although Bella and Connor both live relatively quiet lives with Bella living in London with her husband Max Parker and Connor working around the world as a DJ, they have both responded to the rumours in the past.

In 2016, Bella was asked by New Idea if she still speaks to her parents, to which she replied: "Of course we talk, they're my parents", adding, anyone who says otherwise is "full of sh*t".

Speaking to Woman's Day, Connor described his relationship with his mum as "solid".

"I love my mum. I don't care what people say, I know that me and Mum are solid. I love her a lot. My family means everything," he said.
