It has previously been claimed that Connor and his sister Isabella, 21, have a strained relationship with their mother because of their ties to the Church of Scientology and Nicole - who has children Sunday, five, and Faith, three, with husband Keith Urban - even admitted they don't call her ''mom'' anymore.
