When news broke last week that Bella Cruise’s fiancé Eddie Frencher had joined Scientology inner group Sea Org, no-one was more horrified than her mother, Nicole Kidman. With Scientology insiders explaining that members of the organisation aren’t allowed to marry anyone who’s not a member of the unit, it stood to reason the actress was terrified her 19-year-old daughter would follow her future husband into Sea Org, which also forbids members having children.

Nicole, 45, was already worried about the daughter she adopted with Tom Cruise committing to marry one of the future stars of Scientology. When the latest news reached her, it’s no wonder she panicked. “This is a very strict group,” a source tells Woman’s Day. “Members must sign a billion-year contract to serve the church, and they only make $40 per week for their service.” It’s believed Nicole has been trying to subtly convince Bella, who she’s seen less than she would have liked since her 2001 divorce, that she’s too young to marry.

When she learned of Eddie’s decision, Nic knew she had to do more. “Since Bella’s engagement, Nicole has been making a point to ring her more often, and occasionally managed to bring the conversation around to Bella’s wedding plans,” the source says. “Bella did listen to her mum’s warnings.

“She considered joining Sea Org alongside Eddie, but the thought of such a strict way of life did not appeal to her. Nicole told her to consider what she really wanted out of life and not to commit to a situation she might live to regret. Bella rang her mum this week to say she’d reconsidered… and Nicole was ecstatic.”
