One Direction have revealed they get "annoyed" by constant comments that their friendship is not genuine.

Speaking on Australian TV show Sunday Night, the boyband voiced their frustrations at suggestions their close friendship is all an act.

"It's such a frustrating question," band member Louis Tomlison told the TV show. 

"Because I just don't understand how you can see the way that we are together, on camera and off camera, and look at it as if it's being contrived."

The 'Live While You're Young' singer went on to add that the five-piece band were not skilled enough to act out their closeness.

"Because it's so evident that we do get on so well," Louis added. "And I just don't think we're good enough actors to pull off that kind of friendship!"
