Fans of "NCIS: Los Angeles" will be happy to know that the relationship between Chris O'Donnell and James Todd Smith, aka LL Cool J, shares a similar camaraderie to Callen and Hanna. O'Donnell told Entertainment Tonight Canada their friendship is "similar to the relationship that Todd and I — LL and I — have in real life." The actor noted how he not only respects his co-star but "we also love to torture each other and drive each other crazy." A photograph is shown in the video interview of LL Cool J holding O'Donnell in a headlock!

Similarly, LL Cool J told CBS Watch Magazine how he and O'Donnell compare and contrast. "Like me, he has a family. He's stable, he's settled, he's calm. But we come from different places — me from urban New York, and him from a more Midwestern [background]. So we really complement each other in a lot of ways."

And now, the two friends and co-stars are co-creators of a new reality show, "Come Dance With Me," which premiered in April on CBS (via Variety). O'Donnell said working together so long has helped them collaborate, telling Variety, "There's a shorthand that has evolved over 13 years and a trust, which goes a long way."
