Jake Bugg has said that One Direction make him feel "disheartened".
The 'Seen It All' singer - who has been involved in a war of words with the 'Little Things' group for several months now - said he would never join a boy band as he doesn't consider them real musicians due to their lack of song-writing.
He said: "I would never consider being in a boy band. It's quite disheartening as a songwriter to see those acts."
The 18-year-old musician's comments follow a string of criticism towards the band, previously insisting they don't "have a clue" about music and shouldn't even be "considered a band".
He recently complained: "I don't know how they can really be considered a band, though to be honest. I'm not too sure. I think the more I play on it, it'll wind them up.
"They're there to look good. Music wise? I assume they don't really have a clue. We'll just see. They might do. Probably the ugliest one is the best singer. He might know a couple of [guitar] chords."
It was Jake's dismissal of One Direction being similar to legendary band the Beatles which began their feud, slamming comparisons as nonsense.
"People [call them the new Beatles] because they broke America, but that don't mean a thing. I mean, [One Direction] must know that they're terrible," he said.
"They must know. Calling them the new rock stars is a ridiculous statement. And people should stop making it."
