What is Jillie Mack's net worth?

Jillie Mack is an English actress who has a net worth of $20 million. That is a combined net worth with her husband since 1987, fellow actor Tom Selleck.

Born in December 1957 in Devizes, Wiltshire, England, Jillie Mack began her career as a stage actress. She gained early recognition for her role as Rumpleteazer in the West End production of the hit musical "Cats" during the early 1980s. It was during this time, in 1983, that she met Tom Selleck, who was in London filming "Lassiter" and became a regular in the audience at "Cats." The pair quickly struck up a relationship, and Mack later moved to the United States to be with him.

Their relationship remained largely out of the public eye. The couple married in a secret ceremony on August 7, 1987, at a small wedding chapel near Lake Tahoe, using pseudonyms to maintain privacy. Soon after, Selleck stepped back from the spotlight, leaving his role in "Magnum, P.I." to focus on starting a family with Mack and building a quieter life. In December 1988, they welcomed their daughter, Hannah, who would go on to become a professional equestrian.

That same year, the couple purchased a 63-acre ranch in Ventura County for $5 million from legendary entertainer Dean Martin. The property includes a Spanish colonial-style main house, guest house, underground pool, golf green, chicken coop, hiking trails, large fire pit, and a private helipad. Once a working avocado farm, the ranch suffered during California's droughts, but remains a nature-filled retreat. Mack helps tend to the animals on the property, and Selleck has credited the ranch—and his relationship with Jillie—as his grounding force.

Jillie Mack continued to work sporadically in television throughout the 1980s and 1990s. She appeared in several episodes of "Magnum, P.I." between 1984 and 1985 and also had guest roles in shows such as "The Wizard" (1987), "Tales from the Darkside" (1987), "Hooperman" (1988), "Frasier" (1996), "Fired Up" (1997), "The Queen's Nose" (2000), and "ER" (2002). She also acted in the TV movies "Silverfox" (1991) and "Adventures of Nicholas at Roaring Camp" (1996), and appeared in the video release "Stephen King's Golden Tales" in 1985.

Although she stepped away from acting in later years, Mack played a vital role behind the scenes in her family's life. Jillie Mack remains a private figure who, despite a relatively low public profile, played a key role in one of Hollywood's most enduring marriages.
