Martin Compston's wife, American actress Tianna Chanel Flynn, has put the Scottish actor on a strict no-sugar diet to ensure he fits into his signature waistcoats for the upcoming seventh season of Line of Duty. The 41-year-old will reprise his role as DI Steve Arnott in the hit crime drama, which last aired in 2021.
Compston told the Times that before starting a new project, he follows the Whole30 organic diet, orchestrated by his wife, who is a 'phenomenal cook'. The diet cuts out refined sugar entirely. He said: 'Yesterday she made chicken wings, asparagus, cabbage and a miso sauce for lunch, which all helps me fit nicely into my Steve Arnott waistcoat.'
The actor, who will be joined by co-stars Vicky McClure and Adrian Dunbar, spoke about their off-screen camaraderie. He added that he never tires of fans asking about Line of Duty, saying: 'When I did Sweet Sixteen, for a while it felt like an anchor around my neck because of the pressure of it, whereas Line of Duty came at a time in my career where I’m just proud of it.'
Compston and Flynn married in 2016 and live in Las Vegas with their son. He previously explained on the Table Manners podcast that they chose Vegas to maintain privacy, after experiencing fans taking photos of his child and sending them to him online.
