Lowe and Berkoff — who share two sons: Matthew Edward Lowe, 30, and John Owen Lowe, 28 — married in 1991.

The couple first met on a blind date in 1983 and then worked together years later on the 1990 erotic thriller Bad Influence.

Back in April, Lowe revealed the secret to making his years-long marriage to Berkoff work.

"[Marriage] is hard anywhere, it is not just Hollywood – it's everywhere," he told host Bruce Bozzi on the iHeartPodcast Table for Two with Bruce Bozzi. "Sheryl was and is my best friend. So if you marry for anything other than the fact that is your best friend, you're at a disadvantage from the jump, because that will sustain when the other stuff ebbs and flows."

The Unstable star added that he believes that forgiveness allows a relationship to move forward, sharing, "People say marriage takes work. I'm not sure if it takes work, but what it does take is forgiveness, and being really cognizant of what hill you're willing to die on."

Lowe also said that the physical spark is just as important to keep alive in marriage and a successful long-term relationship.

"I do believe you need the heat for sure," he explained. "If you don't have the heat – and that's a chemical thing – I mean I still have it with Sheryl, you gotta keep the heat."
