NCIS: Los Angeles costars LL Cool J and Chris O’Donnell might be primetime’s newest odd couple, but behind the scenes the two actors have much in common.

“There just wasn’t space to wonder, ‘What’s Chris gonna think of my rap background? Is he gonna be square? Is he gonna get me?'” LL recalls in a new interview with PARADE, because their sameness was quickly apparent.

For Chris, the show couldn’t have happened at a better time. “I definitely had those moments, like any actor, when you get anxious and think, ‘When am I going to work again?'” he confesses. “But I would feel that way even when I had every offer in the world coming to me.”

Once he became a father five times over, however, the feeling was magnified.

LL and wife Simone Johnson have four children: Najee, 20, Italia, 19, Samaria, 14, and Nina, 9. Chris — married since 1997 to Caroline Fentress — is dad to Lily Anne, 10, Christopher, 9, Charles, 6 ½, Finley, 3 ½, and Maeve, 2.

NCIS: Los Angeles airs Tuesday’s at 9 p.m. on CBS.
