We've been loving the latest series of NCIS. Having been on screens for nearly two decades, we're not surprised that Mark Harmon refers to the cast and crew on the series as one big family.

But what about their real families? We did some investigating, and here's all you need to know about the partners and children of not only the stars of NCIS but spin-off NCIS: Los Angeles too…

Mark Harmon

Mark Harmon leads the cast as Leroy Jethro Gibbs. The 69-year-old actor has been in the role ever since the long-running series began and comes from quite a famous family. While his father was the US footballer Tom Harmon, his mother was the black and white movie star, Elyse Knox.

As for his own family, he has been married to actress Pam Dawber since 1987. The couple, who will celebrate their 35th wedding anniversary this year have two sons together, Sean and Ty. Eldest Sean has even appeared on the show playing a young version of his father's character in flashback episodes.

Wilmer Valderrama

Wilmer Valderrama joined the cast as agent Nicholas Torres in 2016. The actor has had quite a number of high-profile relationships over the years, notably with Lindsey Lohan and Demi Lovato.

In 2020, he announced his engagement to his girlfriend of eight months Amanda Pacheco, and shortly before Christmas, the couple confirmed that they will welcome their first child, a baby daughter, later this year.

LL Cool J has starred in NCIS spin-off series NCIS: Los Angeles as Sam Hanna since the early noughties. Away from the cameras, he has been happily married to wife Simone I. Smith since 1995. The two met when LL was a young rapper and dated for eight years before tying the knot.

They share four grown-up children together – son Najee, 31, and daughters Italia, 30, Samaria, 25, and Nina, 20. While LL's three eldest children have pursued careers away from the limelight, youngest Nina has decided to follow in her famous dad's footsteps and is an aspiring R&B singer.

Last year, in their first public appearance as a couple, Maria announced that she and chef Dominique Crenn had become engaged while on a romantic break to Paris.

While his character recently experienced a family tragedy, in real-life Brian is happily married to wife Kelly with whom he shares two children. He tends to keep his personal life away from the spotlight, so not much is known about the family.

Chris O'Donnell
