The 19-year-old DJ insisted rumours he is estranged from the Australian actress - who adopted him with then-husband Tom Cruise in 1995 - are wide of the mark and says his family mean ''everything'' too him.
He told Australia's Woman's Day magazine: ''I love my mum. I don't care what people say. I know that me and mum are solid. I love her a lot. My family means everything. Yeah, I love my music, but the family comes before everything else.''
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.
Speaking in 2007, she said: ''My kids don't call me mommy, they don't even call me mom. They call me Nicole, which I hate and tell them off for it.''
She has also spoken of her sadness that the children opted to live with Tom after they separated in 2001.
She said: ''They live with Tom, which was their choice. I'd love them to live with us, but what can you do?''
