X Factor winners James Arthur and Matt Cardle have continued to show how credible they are by slagging one another off on Twitter and in the press.
Let's start by going back to the beginning.
James pissed off Matt by branding all other male winners a bit rubbish, basically.
He said: "The blokes that have won before have had a niche, they haven't sold records because they haven't made great albums. That's the bottom line."
Matt didn't like this and hit back: "I said, 'Look, James, you're very talented but you haven't sold two million records yet, which I have.'
"You haven't had two top ten albums yet, which I've had. Don't start mouthing off before you've even really left the show."
Matt went on: "I doubt he's even listened to my albums. It's a shame and I hope it doesn't do him too much damage.
"Not only has he offended me but he's offended every other person that's won the X Factor and everyone who works or has written on these albums.
"That's some of the best songwriters in the world - all these people - and he's now rubbished their work. So it's a pretty s*** thing for him to have said."
So, that brings us to yesterday when James took to Twitter to brand Matt desperate for press.
He tweeted: "2 million returned and now live in the bargain bin at asda give it up the tunes are brutal.. the desperation for press is embarrassing."
James added: "Get bummed.. Some more."
The boys are definitely showing just what authentic and credible artists they are.
