Don Johnson thinks a good marriage will keep you young. The 74-year-old actor wed his wife Kelley Phleger, 56, in 1999, and has now emphasised finding the right partner is the key to avoiding draining stress. He told People magazine: “A bad marriage will age you!” The ‘Miami Vice’ actor - who has 41-year-old Jesse with his former partner Patti D’Arbanville, 34-year-old Dakota and his 39-year-old stepson Alexander Bauer with his ex-wife Melanie Griffith, and Atherton, 24, Jasper, 22, and 18-year-old Deacon with Kelly - heaped praise onto his “amazing” spouse, and said his six children also played a big part in keeping him in such good shape.

He joked: “Keep moving. How else do you think I have six kids? That I can name anyway.” Don provided an update on his children and said they were “doing alright”.

He added: “They’re all out of the house, but they always come back. “Some of them never leave! And honestly, you don’t want them to leave. At least I don’t.

” The ‘Knives Out’ star shared that spending time with his family was far more important to him than working, and so would often try to choose smaller roles to prioritise his loved ones. He explained: “Work-life balance is an interesting thing as an actor because movies eat your life. Television shows eat your life.

“Luckily, I’m at a place where I can pick and choose roles, and sometimes I often prefer the supporting role because I still get joy out of what I do, but I don’t alway.
