The couple have been married since 2014 and live in a stunning Cheshire home together.
Adam said that although some people can be “brainwashed” into having children together, he and Katy are happy with their three dogs.
Katy added: “I didn’t really bat an eyelid. I was like, ‘Oh, that’s a shame, but we’ve got each other.’ I know having kids is very important for a lot of people, so it’s almost a good thing it happened to us.”
Earlier this month Adam opened up on his struggle with mental health, which left him feeling suicidal for 17 years.
