Kevin himself told Metro.co.uk in a red carpet interview that the biggest challenge of making the show is being away from his family.
‘The challenges aren’t what you really think,’ he explained.
‘They’re from being away from home, that’s a challenge. The kids are growing up and you want to see everything they do.’
