The statement concluded with the estranged couple thanking their followers for "supporting us as we continue to make the health and happiness of our family a priority."

"It’s funny: I've shown my kids the show," he told GQ in January 2024. "I let them watch season one – but I wouldn’t let them see the naked guy hanging crucified on the wall [who had his bollocks chopped off and was forced to swallow them whole], but everything else was… Within context, it all made sense."

He added: "They loved it, man. For me, it’s not ‘Dad TV’, it's ‘family TV’. I walk down the street and little ladies on their walkers are like 'Reacher… Reacher…' It’s such a misnomer to me to qualify this as ‘Dad TV’. But I am a father and I, too, love the show. Maybe it does work.
