These Are The NCIS Cast's Actual Partners

Coming just behind NBC's "Law & Order: Special Victims Unit," the CBS procedural "NCIS" ranks as the second longest-running current American TV drama as it approaches two decades on the airwaves. And some of its cast members' real-life relationships have lasted even longer!

Mark Harmon and his wife have been married since the 1980s, for example, and "NCIS" viewers even got to see them share the screen in the show's 18th season. Actor David McCallum, meanwhile, has been a married man for two decades longer: He and his wife got hitched in the 1960s! And it turns out that many "NCIS" stars have significant others with significant credentials. One actor fell in love with an award-winning chef, another is married to a high-powered architect, and another is hitched to the filmmaker son of actress Sophia Loren!

Here's what you need to know about the love lives of popular "NCIS" stars.

David McCallum — who plays Donald "Ducky" Mallard on "NCIS" and starred as Illya Kuryakin on "The Man from U.N.C.L.E." — married Katherine Carpenter, a former model, in 1967. The two have a son and daughter, according to The Scotsman. They also had eight grandchildren by 2015, when McCallum spoke with the Los Angeles Times. "We have six boys in New York and two girls here," he said at the time, joking, "I keep the boys and the girls on different coasts so I can keep them straight."

The actor was previously married to the late British actress Jill Ireland, with whom he welcomed two sons and a daughter, The Scotsman reported. Ireland even joined McCallum on screen in "The Man from U.N.C.L.E.," playing three characters in the spy drama.

Ireland married McCallum's "The Great Escape" co-star Charles Bronson, but McCallum bears no ill will. "I never hated him, Charlie was always a good friend," he told Daily Record in 2016. "I find that when problems come along, worrying about them and getting anxious and negative is quite unnecessary. You can solve them, usually amicably. That's what happened."

Mark Harmon, who plays Leroy Jethro Gibbs on "NCIS," married "Mork & Mindy" star Pam Dawber in 1987, as the Associated Press reported at the time, and they've been together ever since. "We were both in our thirties when we got married, so hopefully the stupid stuff we did earlier," Harmon told People in 2019. "That's probably the closest I have to what the key is."

Dawber, who also starred on the 1980s sitcom "My Sister Sam," stepped out of the spotlight after tying the knot with Harmon. "I don't think two people can work all the time in show business and stay married," she told Entertainment Tonight in 2016. "I did everything you can do in this business, and then I had children and it's like, 'I'm not going to chase this fame thing.'"

Harmon and Dawber have two children together, sons Sean and Ty, the former of whom has played young Gibbs on "NCIS." The CBS drama really is a family business, as Dawber guest-starred in Season 18 as investigative journalist Marcie Warren. But despite the chemistry the two no doubt have, Dawber assured Entertainment Weekly ahead of time that her scenes with her husband were "not going to be romantic."

Rocky Carroll, who joined "NCIS" as Leon Vance midway through Season 5, is married to Gabrielle Bullock, as the Los Angeles Times noted in a 2018 piece about her. By that point, the couple had been married for 22 years. Together, they have a daughter named Elissa.

Bullock is an architect and the head of global diversity in Los Angeles for the architecture and design firm Perkins+Will. "I'm an architect, so I lead projects 50% of my time," she told the Times. "The other 50% of the time I'm the firm's director of global diversity. I lead the strategy, monitor it, lead the diversity council that we have and try to build a more inclusive culture for the firm." The New York City native is a graduate of the Fiorello H. LaGuardia High School of Music & Art and Performing Arts and the Rhode Island School of Design. By the time she graduated RISD in 1984, she was the school's second female African-American graduate, the newspaper reported.

Bullock is also the vice president of the Southern California chapter of the International Interior Design Association, according to the organization's website. Still, if you Google her name, "you get Rocky Carroll," she told the Times with a laugh.

Maria Bello, who played Jack Sloane for a few seasons before her exit from "NCIS" in 2021, got engaged to Dominique Crenn, the only female chef in America who has three Michelin stars, in 2019, according to a 2020 Haute Living feature.

Crenn gave the magazine her and Bello's origin story, saying the actress reached out via Instagram DM to ask for a reservation at Crenn's restaurant. "I didn't really know who Maria was, but I'm French, so I don't know really follow American actresses," she said. "I'm like, 'Who is Maria Bello?'"

Nevertheless, Crenn granted a reservation to Bello — who has a son with ex-boyfriend Dan McDermott, per Us Weekly — and the duo stayed friends for a year before they took their relationship to the next level. When Bello finally told Crenn she was in love with her, the chef disclosed to her future fiancée that she had been diagnosed with breast cancer. "She was like, 'I'm really fun around sick people,'" Crenn recalled to Haute Living, adding, "And I'm telling you, she kept her word. It's one of the most beautiful love stories. I couldn't even write this for [a] movie; it's so much better."

The actress behind "NCIS" character Kasie Hines, Diona Reasonover is married to actress and writer Patricia Villetto, as she revealed to the New York Post in 2018, after she was promoted to series regular on the show. "I don't know why it didn't occur to me that I'd be in the opening credits, so I freaked out so much. [Patricia and I] were both like, 'What?!'" she told the paper. "Now she won't let me talk during 'NCIS.' I try to tell her funny stories, like, 'Oh, you know what's funny about this scene?' And she's like, 'Shush, shush, shush, shush, shush. Don't talk to me; I'm watching my show.'"

Villetto's Second City bio reveals she graduated from the University of Ulster in Northern Ireland — where she studied "acting, playwriting and art of Irish bulls**ting" — while her Instagram bio touts that she's also a "writer, director, actor, improviser, comic, waitress and Dolly Parton lover." According to her IMDb profile, Villetto has written for projects like "Swamp Talk with Shrek & Donkey," "Kung Fu Panda," "So Shook," "Mega Man: Fully Charged," "Ben 10," and "Tigtone."

Sasha Alexander, who portrayed Caitlin Todd across dozens episodes of the CBS procedural between 2003 and 2012, tied the knot with Edoardo Ponti in 2007, according to People. Ponti's mother is Oscar-winning Italian actress Sophia Loren, star of films like "Two Women" and "Marriage Italian Style."

Alexander and Ponti met at film school at USC but didn't start dating until her "NCIS" days, as the actress told TV Guide in 2012. "He was always lovely — he had a smile that gave me enormous comfort, even though I didn't know him." He went up to her at a restaurant years later, and they finally started a relationship. "Eight years later, I'd worked an all-nighter on 'NCIS,'" she recalled, "and I was sitting in a restaurant eating breakfast with a hat on, and he walked up to my table and said, 'Sasha, do you remember me?'" The couple now has two children, per People. They welcomed daughter Lucia Sofia in 2006 and son Leonardo Fortunato in 2011.

Ponti is also in showbiz: He's a filmmaker who wrote and directed the 2020 film "The Life Ahead," which stars his famous mother. Loren also appeared in his films "Between Strangers" and "Voce Umana," or "Human Voice," while Alexander starred in his film "Coming & Going."

On "NCIS," Emily Wickersham played the utterly no-nonsense Agent Bishop, but the actor herself keeps things comparatively quite low key. Wickersham's long-time partner is fellow actor James Badge Dale, who's appeared in multiple high-profile projects over the years, including "24" and "The Departed." However, the couple doesn't over-share on social media, preferring to give fans glimpses into their relationship only every now and then. In fact, Wickersham casually revealed she was pregnant once she was already pretty far along. 

Baby boy Cassius was born December 30, 2021. Wickersham shared the happy news on Instagram alongside shots of her and Dale spending some quality time with the newborn, writing, "You are more than @jamesbadgedale and I could ever have imagined. We are so in love with you." 

Wickersham was previously married once before to musician Blake Anderson Hanley. The couple split after eight years, per Express, so that might explain her reluctance to reveal too much online. 

Robert Wagner has had a massive career beyond the confines of "NCIS," but his romantic life has had its ups and downs. The veteran actor has been married four times to three different women, beginning with the late actress Natalie Wood. They split amid rumors he'd been unfaithful, and officially divorced in 1962 (via Biography). The following year, Wagner married actor Marion Marshall, with the happy couple welcoming daughter Katie in 1964.

Their marriage lasted until 1971, which left Wagner open to rekindle things with Wood, who had split from her own paramour around the same time. They remarried in 1972 and welcomed a daughter named Courtney in 1974. In 1981, Wood died under mysterious circumstances, leaving Wagner devastated. Notably, he remains a person of interest in her death, per The New York Times. 

Wagner focused on being a father until he found love again with fellow actor Jill St. John, who had lost her own husband and found common ground with the "NCIS" star. The two got hitched in 1990 and have been together ever since. Similarly, St. John had also been married three times previously.
