"I love my mum," the aspiring DJ told Woman's Day Australia in a recent interview.
"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," the aspiring DJ said.

Kidman and Urban are parents to daughter Sunday Rose, 5, and Faith Margaret, 3.
