The 19 year old was adopted by Kidman and her now ex-husband Tom Cruise in 1995, along with his sister Isabella, who was taken in by the Hollywood couple two years earlier.
Kidman now lives in Nashville, Tennessee with her husband Keith Urban and their two daughters, and Connor has rarely been seen with his mother over the last few years, prompting rumours of an estrangement, but the teenager is adamant he has a good relationship with the Oscar winner.
He tells 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... Family comes before everything else."
