THE adopted daughter of Nicole Kidman and Tom Cruise is reportedly on the verge of leaving the Church of Scientology after her boyfriend's recent defection from the controversial religion.

Isabella Cruise - who continued practising Scientology after Kidman and Cruise split in 2000 (which is long believed to have driven a wedge between her and her mother) - is said to be following the path of boyfriend Eddie Frencher, who has left the organisation's highest order, known as Sea Org, and was supposedly shunned by members for doing so.

According to US site Celeb Dirty Laundry, Isabella hopes to marry Frencher eventually.
