Budding DJ Connor Cruise, who was adopted by the actress and ex-husband Tom Cruise, has reportedly reached out to the 'American Idol' judge, as he wants to remix one of the country singer's songs.
A source said: "Connor felt like he never had the chance to connect with Keith; this is the perfect opportunity.
"Keith was shocked, but more than anything, he was flattered."
Oscar winner Nicole, who has adopted daughter Isabella, 22, with Tom and daughters Sunday, six, and Faith, four, with Keith, is thrilled that Connor is forming a bond with his stepfather.
The insider said: "Family is everything to Nicole, and she's always wanted her son and Keith to have more of a bond.
The 46-year-old beauty has encouraged Keith to show his support even if he doesn't like the remix.
The source added to US OK! magazine: "Nicole keeps saying he just has to go with it."
It was previously claimed that Connor, 19, and aspiring artist Isabella had a strained relationship with their mother because of their ties to the Church of Scientology and Nicole admitted a few years ago that they had stopped calling her "mom".
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."
But DJ Connor insisted last March that he had a "solid" relationship with the actress.
He said: "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."
