Simon Cowell
During COVID-19, the 65-year-old music mogul revealed he had not used a smartphone in "three years".
In 2020, the X Factor judge told Entertainment Tonight: "It means you don’t wake up to, like, 50 text messages you can’t reply to.
"And that’s what happened one morning – I woke up and I've got 52 unread messages.
"And I thought, even if I reply to every one of those, I’m going to get another replying back, and then I'm going to get more that day.
"And I realised it was actually stopping me from working or living properly, so I just turned it off and I went a month, three months, then a year, then two years, then three years – and I love it."
