But on Sunday, he apparently took to Twitter with a tweet that seems to have been inspired by the collapse of his dad's marriage to Katie Holmes.
"#LaFamilia Always. Friends Come And Go, But Family Is Forever," the 17-year-old retweeted.
And a friend of the Hollywood offspring now tells me...
They're not surprised by Connor's post.
"He is very close to his family," the friend said. "But he is also very down to earth and you would never know he was the son of Tom Cruise and Nicole Kidman."
The friend described Connor as "a very well-adjusted kid," who is also close to his sister Isabella.
As for Holmes, Connor never "truly got close" to his stepmother, nor does he talk about her or Suri much—at least not publicly, the friend said.
Connor is an aspiring deejay who commands a minimum of $5,000 to spin tunes for an event.
His gigs—he goes by the name DJ C-Squared—have included the opening of the New Era flagship store in West Hollywood, gay bar The Abbey's Oscar viewing benefit for AIDS Project Los Angeles and a Hollywood bash celebrating the launch of McDonald's Chicken McBites.
