Ever since Little Mix split from Simon Cowell's record label Syco, things seem to have turned sour and now things have gotten even worse.
While they all keep having sly public digs at each other, earlier this month the drama was heightened, following Simon's decision to SCRAP the X Factor: All Stars series and instead launch X Factor: The Band.
It all looked slightly dodgy, especially after the news was announced just days after Little Mix revealed they had a new BBC One talent show coming out - also aiming to put together the next biggest group in pop.
Well, well, well.
AND NOW, Simon has reportedly thrown EVEN MORE shade at the Little Mix show by telling a contestant during an X Factor: The Band audition that they should apply for his rival show, suggesting it would get all of their rejects. SAVAGE.

He told the same publication, “This is what really happened. I was approached to co-produce that show last year by Little Mix’s management.
“I told them the problem was, we have a conflict of interest because we are launching X Factor The Band in 2020. We were told their show was going to launch in 2021."
