The Succession star, 50, recently marked his 21st wedding anniversary with Keeley Hawes, 49, whom he met in 2002.
Matthew and Keeley are proud parents to their daughter Maggie, 20, and son Ralph, 19. Additionally, Matthew is a stepfather to Keeley's son Myles, 25, from her previous marriage.
Despite their strong marriage, Matthew revealed that Keeley once threatened him with divorce over something unusual related to his work on Succession.
While filming in America’s Southwest, Matthew tried to embrace the local culture, which raised concerns for Keeley.
“We went to Sante Fe [in New Mexico] to the high desert.”
“I remember ringing Keeley and saying, ‘Do you think I’d get away with buying cowboy boots?’”
Keeley, known for her role in Line Of Duty, apparently had reservations about his plan.
Matthew Macfadyen’s playful attempt to adopt cowboy culture nearly cost him his marriage, revealing a humorous yet telling moment between the couple.
