The hairstyle divided fans, with some gushing about the transformation, while others claimed it had “aged” him.
John spoke out about the response to his appearance during an appearance on The One Show.
He said: “I wore a hat for a little while. I went back into the I’m A Celebrity jungle about a week ago, and I revealed it. The press thought, ‘There’s something wrong with him. He’s ill.’
“I’m like, really? I just cut my hair. I just wanted a change. I’ve been dyeing my hair since I’ve been in my twenties. I wanted to go with the silver fox.”
