The drummer explained that his mother and father were initially sceptical about him entering the 'All About You' band at a young age, but started to support him when they saw how confident he was of their chances of success.
"My parents weren't keen on me joining McFly," he admitted. "I was 17 and I was about to do my AS levels. My dad really wanted me to finish school and do a degree, but I argued that doing this was the experience I needed.
"It was weird, because once I'd met the other guys I never had a second of doubt that we were going to make it. My parents were incredible - after a few sessions they just said they'd support me."
Judd added that he couldn't wait to begin working with the group again now that Strictly has come to an end.
"The McFly boys have been recording new material and demos while I have been doing this. Obviously Dougie has been in the jungle. We will be happy to get back into the studio and touring in March and April. And we can't wait to get back on the road. I'm happy to be back on drums.
"Dancing on Strictly is ten times more nerve-racking than being on stage with McFly. When we've had high-pressured gigs I've always thought I'm so glad I'm a drummer. But Strictly has given me more confidence."
