That's not the way it works."

In March 2018, Colin Firth's wife Livia Giuggioli came forward saying that she'd had an affair with a childhood friend, journalist Marco Brancaccia, while she and her husband were briefly separated.

Soon after Princess Diana's affair was made public, so was Prince Charles' own daliance with his lifelong friend Camilla Parker Bowles.
