NCIS might be about solving military-related crimes, but audiences have stuck around for 22 seasons because of the show’s cast of characters (and their love stories).

Fans mourned alongside Anthony DiNozzo (Michael Weatherly) when Kate Todd (Sasha Alexander) was killed in season 2, and rejoiced when he and Ziva David (Cote de Pablo) finally became an item in season 10. Meanwhile, viewers spent years rooting for a Tim McGee (Sean Murray) and Abby Sciuto (Pauley Perrette) romance before he married Delilah Fielding (Margo Harshman) in season 14.

More recently, fans were devastated when Ellie Bishop (Emily Wickersham) betrayed Nick Torres (Wilmer Valderrama) in season 18, and they’re now watching the love story between him and Robin Knight (Lilan Bowden) unfold in season 22 — with new episodes airing every Monday on CBS.

Off-screen, many of the NCIS cast members (past and present) have maintained long-lasting relationships. Mark Harmon, who left the show in 2021, has been married to Pam Dawber since 1987, while Brian Dietzen and his wife, Kelly Dietzen, have been going strong since 2004.

Here’s everything to know about the real-life partners of the NCIS cast.
