Dave and Liliana kept their personal life incredibly private after they tied the knot back in 2011 at the star's hometown in Barrow, Cumbria.
But thanking his carers with a special Christmas dinner as part of a Hairy Bikers episode this Christmas, he opened up about just how vital Liliana had been to his care.
Speaking about his cancer diagnosis, he said: 'It impacts on the family. It's so difficult for my wife and family you know, that not knowing, your future is completely turned upside down.
'And also I think for my wife as well, it gave her some freedom away from me. I felt good about being able to let her have time to herself, albeit to go to the gym or a spa, just to have some of her time, because it's been so all-encompassing.'
