The boyband said that the 5* series McFly on the Wall is considerably different from Kerry Katona and Peter Andre's Next Chapter formats, claiming that they were more inspired by traditional documentaries.
"Our references were... and don't get me wrong...we're probably not even close, but our references were Riding Giants and Dogtown and Z-Boys," said Harry Judd. "More documentaries than reality shows."
Tom Fletcher added: "None of our show is set up. I would never do a camera shot that's been staged. We've been steering away from that and wanted to stay clear of that."
Dogtown and Z-Boys was a cult hit in 2001. Directed by Stacy Peralta, it looked at the history of skateboarding and was narrated by Sean Penn. Riding Giants was a 2004 film that traced the origins of surfing.
Joking about the "cheesy" title of their series, Fletcher said: "It was either that or McFly Unzipped and that's even more cheesy!"
Dougie Poynter joked: "I wanted to call it McFly's Awesome Breakdancing DVD."
McFly on the Wall starts tonight at 10pm on 5*.
