Troian Bellisario Had a Crush on One of Her Stepsiblings before They Met

Troian Bellisario comes from a family of several actors with whom she has shared the screen on numerous occasions. The actress was born to an acclaimed TV and film producer who remarried a few times, creating a blended family of entertainers.

Troian Avery Bellisario drew her first breath in Los Angeles County on October 28, 1985. At age three, she debuted in the acting industry, appearing in the 1988 crime drama "Last Rites" as Nuzo's Daughter. The film was written and directed by her father, Donald P. Bellisario.

Troian continued growing up in front of the camera in TV shows and movies, primarily starring in productions led by Donald, until she landed the role she would become most famous for, as Spencer Hastings in "Pretty Little Liars." However, the actress hasn't been the only one in her family captivating audiences on-screen.

Troian Has 6 Siblings: 1 Brother, 3 Half-Siblings, and 2 Stepsiblings

Given the lack of information regarding some of them, little chunks of Troian's family tree remain a mystery. According to several sources, she has familial connections to six siblings, most of whom are also actors. Her only biological brother is Nicholas Bellisario, born to Donald and her mother, actress Deborah Pratt.

Apart from his relation to Troian, little is known about Nicholas. And despite having an IMDb page, no credits were listed under his name at the time of publication. Before Troian and Nicholas came along, their dad had been married to Lynn Halpern. The former couple, who divorced the year before Troian arrived, welcomed her older half-brother, Michael Bellisario.

Michael was born on April 17, 1980. He's best known for his role on the '90s crime series, "JAG," and he appeared in 2007's "The Picture of Dorian Gray." When Troian portrayed Nuzo's Daughter in "Last Rites," Michael played Nuzo's Son, marking their earliest collaboration.

Julie B. Watson, born Julie Bellisario, is known as Troian's half-sister, born to Donald and Margaret Schaffran. Like Michael, Julie appeared in "JAG" and later joined the casts of the '80s sci-fi series "Quantum Leap" and "NCIS." Her biological brother is David Bellisario, though, like Nicholas, it appears he never joined the entertainment industry.

Trioan's father's last known marriage was to Vivienne Bellisario, who had sons (Trioan's stepbrothers) Sean Murray and Chad W. Murray — not with Bill Murray — before marrying the producer. Both brothers are actors, with Sean primarily renowned for his longtime role as Tim McGee on "NCIS" and "NCIS: Los Angeles," alongside LL Cool J and David McCallum.

Troian Often Shares Heartwarming Posts in Honor of Her Brother Michael

The Hollywood star hasn't missed an opportunity to celebrate her love and poke fun at Michael on social media, whom she has affectionately called a "dork." Their bond has grown strong since Troian was born, as she wrote on a birthday tribute in 2021, detailing all the ways Michael stayed present as an older brother. She penned another in 2022, saying:

"Happy birthday to the closest thing to a love child between Pee Wee Herman and Michael Corleone."

Troian Had a Crush on Sean Murray before He Became Her Stepbrother

Although Sean is chiefly known for his role in the "NCIS" series, he captured many hearts as a teen when he starred as Thackery Binx in 1993's "Hocus Pocus," alongside Thora Birch, Bette Midler, and Sarah Jessica Parker. Thackery became the object of 8-year-old Troian's affection when the film came out, as he was for many other young girls.

During a February interview this year, Sean revealed that Troian acted "a little weird" when they were first introduced as stepsiblings. She later admitted he'd been her crush when she was younger and was "trying to work that out." The pair later co-starred on "NCIS," as Troian played Tim McGee's sister.
