Breaking News:Nicole Kidman’s kids with Tom Cruise skip her big night, as she seems to reference marriage to ‘Top Gun’ star

While her daughters with Keith Urban, Sunday Rose and Faith Margaret, were present for the event, her two adopted children with Tom Cruise, Connor and Isabella, were absent.

Kidman has a reportedly strained relationship with the children, in part because of their participation in Scientology, alongside Cruise.

Regarding their relationship with her and the controversial religion, Kidman spoke with Australia’s WHO magazine in 2017, saying, “I have to protect all those relationships. I know 150 percent that I would give up my life for my children because it’s what my purpose is.”

“They are adults. 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 continued. “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. 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.”

Kidman and Cruise adopted Isabella in 1992 and Connor in 1995. During their divorce in 2001, they shared joint custody.

According to The Daily Mail, the children were “loyal to their father” and decided to live with him.
