The stars of NCIS have kept fans captivated for years, both on and off-screen. While Mark Harmon, Pauley Perrette, and Cote de Pablo are known for their unforgettable roles as Gibbs, Abby, and Ziva, their real lives hold some fascinating and cherished secrets that even loyal fans might not know.

Mark Harmon, the backbone of NCIS as Leroy Jethro Gibbs, is as private in real life as his stoic character. A little-known fact is that Harmon once turned down high-profile roles to prioritize family life with his wife, actress Pam Dawber, and their two sons. An accomplished carpenter in his free time, Harmon even builds furniture as a hobby—adding a humble, grounded layer to the Hollywood icon.

Pauley Perrette, who brought the quirky and lovable forensic scientist Abby Sciuto to life, is a talented musician and philanthropist. Beyond her acting career, Pauley has a degree in criminal science, which perfectly aligned with her role. She’s also passionate about animal rescue and uses her platform to advocate for causes close to her heart, showcasing a softer, more compassionate side to her edgy persona.

Cote de Pablo, beloved for her portrayal of Ziva David, has a secret talent for singing. Before her acting career soared, Cote showcased her incredible vocals and even performed a soulful rendition of “Temptation” in a Season 6 episode of NCIS. Away from the spotlight, she’s known for her close-knit friendships with her co-stars, particularly Mark Harmon, whom she credits as a mentor and guiding force in her career.

These cherished secrets reveal a deeper, more personal side to the stars who helped make NCIS one of the most beloved shows in television history. Their off-screen talents and personalities remind us why fans continue to adore them long after the cameras stop rolling.
