The boys opened up about their friendship with the One Direction boys; Harry Styles, Louis Tomlinson, Niall Horan, Liam Payne and Zayn Malik - whom they have written songs for in the past - who they admire for their ''genuine'' nature.
Dougie told New! magazine: ''It's all very natural and they're very genuine. I think that's why they've exploded.''
Danny added: ''We asked them for advice! ''How do you do it? How do you look so good?''
The 'All About You' singers find the pressures of pop stardom a difficult way of life, but say they experienced new levels of attention when spending time with One Direction boys.
Tom said: ''It's as difficult as every other job. But I'm sure there's a guy cleaning up a toilet that has a much harder life than we do.''
Harry agreed: ''We can't complain. But when we've been with One Direction, it's another level for them.''
While One Direction have just finished their worldwide Take Me Home tour, Mcfly - who recently united with former Busted members Matt Willis and James Bourne to form supergroup McBusted - will embark on a sell-out UK tour next year.
