Tom Selleck first met Jillie Mack while she was performing in Cats in 1983.

Selleck was at the height of his fame when he met Mack while she was performing in the musical Cats. They got married in 1987, and soon after, he quit Magnum, P.I. so they could start a family and live a quieter life on a ranch in Ventura, California.

He later returned to acting but has always focused on his family.

So, who is Tom Selleck’s wife? Here’s everything you need to know about Jillie Mack and her decades-long relationship with the actor.

Mack spent her mid-20s starring in the West End musical Cats as Rumpleteazer. This musical was an essential moment in Mack’s career and led to her meeting Selleck.

On 7 August 1987, the pair married at a Victorian-style wedding chapel open at all hours near Lake Tahoe in Nevada. Only a few family members were there, including Selleck’s brother, Bob, who had arranged everything with fake names so that the public and the media wouldn’t know who was getting married. Even the minister didn’t know what was happening; they expected a “Tom Jenkins” and a “Suzie Mark.”

A local Nevada newspaper ran a story about the celebrity couple’s wedding a month later, telling the world about their private ceremony.

Before he married Mack, Selleck was married to actress Jacqueline Ray for 11 years, and they got divorced in 1982.

On 16 December 1988, the couple had a daughter, Hannah Margaret Selleck. Hannah spent most of her childhood on their family ranch, where she learned how to care for horses.

She is a successful horse rider who started competing when she was 10. She has competed professionally in both the hunter and jumper rings at the international level. In 2012, she set up her own horse farm, Descanso Farm, which helps horses prepare for shows.

After Hannah was born, the couple moved out of the spotlight to focus on their family, moving to a private ranch in Ventura, California. The 65-acre property has a horse corral and was once a working avocado farm, which Selleck tended to himself until the California droughts killed all the trees.

Although her acting career in the UK had ended, Mack still appeared on several TV shows in the US. She even made several cameo appearances on Selleck’s hit show Magnum, P.I., in seasons 4 and 5. She also appeared in an episode of the ’90s sitcom Frasier and the medical drama ER.

Even before Selleck and Mack got together, the Blue Bloods actor made sure to clearly distinguish his public and personal life.
