A Scientology insider has made the startling claim that Tom Cruise's adopted children, Isabella and Connor Cruise, were "indoctrinated to hate" their mother, Australian actress Nicole Kidman. The claims have been denied by the Church of Scientology.
The allegations come from Sam Domingo, the daughter-in-law of the world-famous opera singer, Plácido Domingo, who spent 22 years in the Church of Scientology.

Ms Domingo, 51, frequently associated with Tom Cruise's family and other celebrities when visiting the International Celebrity Centre in Los Angeles.
She claims her children were close with Connor and Isabella, and that she herself was friends Tom's sisters Cass Mapother, Marian Henry and Lee Ann DeVette.
According to Ms Domingo, Isabella and Connor Cruise appeared to be normal children at Scientology's Celebrity Centre until Tom and Nicole divorced in 2001.
Isabella and Connor were relocated to an isolated "boot camp" and reportedly placed under constant supervision of Scientology No 2 and enforcer Marty Rathbun, who is no longer part of the Church of Scientology.
The children were told their mother was a "Suppressive Person" and that they should keep her at a distance, Ms Domingo claims.
"I know what techniques they used... I know what the second-in-command at the time, Marty Rathbun did, he was so tough on them, the Cruise kids had no choice.
"After the divorce, they were indoctrinated into Scientology and very much isolated," Ms Domingo said.
"The whole Cruise family got ordered back to LA when he divorced Nicole, as they were studying in Florida at the time," she added, which was when the indoctrination of hatred towards the Big Little Lies actress supposedly began.
Scientology whistleblower Tony Ortega told The Daily Beast: "Isabella and her brother Connor grew up in the Church of Scientology. Their mother, Nicole Kidman, was allegedly targeted by the Church because of their fear that she was turning her then-husband against them."
A similar situation occurred between Tom Cruise and his ex-wife Katie Holmes with their daughter, Suri Cruise.
"You can't be anti-Scientology if you're part of Tom's family, you will be disconnected - look at his daughter Suri," Ms Domingo said.
The Top Gun actor hasn't seen his daughter Suri since 2013, and has reportedly not reached out to her in any way since.
Ms Domingo initially kept quiet about the supposed indoctrination of hatred towards Nicole Kidman out of loyalty to the Cruise family.
However, it was the new Scientology promo featuring Cruise's daughter Isabella, 26, that inspired her to come forward.
She claimed that Isabella was being "used" as Scientology's "poster girl."
In the promo, Isabella thanked the Church and said, "This IS what I had been searching for. The missing piece. Suddenly everything began to make sense."
Ms Domingo claims the Church of Scientology is using Isabella to promote themselves.
"Isabella's being used for PR, she's Tom Cruise's kid, it's not fair what they're doing to her and Connor. They have no choice but to be the poster kids of Scientology now," the 51-year-old said.

Ms Domingo is now out of the Church, along with her three daughters, and claims her story should serve as a cautionary tale about the dangers of Scientology.
A spokesperson for the Church of Scientology has denied Ms Domingo's claims, accusing her of lying at length about the Scientology religion, Daily Mail reports.
