Little Mix fans have taken aim at Louis Walsh for seemingly throwing shade at the girls.
It's after Louis praised Four Of Diamonds' latest live performance, remarking: "We’ve finally got a girl group where everybody sings – we haven’t had that in a long time."
Clearly Louis wasn't watching last year's show where 4th Impact stormed the stage and he also forgot Little Mix, who are currently Number 1 in the charts.
In fact, this week the girls became X Factor's most successful winners ever with four Number 1s to their name.
On Twitter, Mixers hit out at Louis' remark with one writing: "Did not like that comment @TheXFactor @LittleMix are amazing singers and all can sing #XFactor"
"A girl group where everybody sings for the first time" Louis, little mix only bloody won the show, what a cow #XFactor," another remarked.
Another added: "We've got a girl group where everybody sings, that hasn't happened in so long" says Louis, who I guess hasn't heard of Little Mix #XFactor"
Despite Louis' praise for Four Of Diamonds on the main show, on the Xtra Factor he was caught out a bit for seeming to FORGET them.
Speaking of his other group 5 After Midnight in front of the girls, Louis declared: "I'd like to say something, I think they're the best group I've ever worked with on X Factor."
However, his lack of regard for Four of Diamonds didn't go unnoticed.
Presenter Rylan Clark-Neal stuck up for the girls, asking: "How do you think they would feel after hearing that?"
Louis then tried to backtrack, responding: "They're the best boyband. Boyband!"
It just wouldn't be The X Factor without Louis, let's be honest.
The show returns to ITV tonight at 8PM with the latest results.
