When it was announced Grimmy was leaving his role of X Factor judge and mentor after just one series, the DJ claimed there was "no bad blood" and insisted he "genuinely loved it" and he was the one who chose to quit.
But now a dramatic sounding source has waded in and told Sun Online: "Grimmy has been a dead man walking for a long time." Woah.
The insider reckons that although Simon Cowell was one keen bean when it came to getting Nick and Rita Ora on the panel, in a bid to help appeal to a younger audience, he changed his mind "almost immediately" about Grimmy after the first episode aired!
"There was even talk of getting rid of him mid series, but that would have been too embarrassing," the source continued.
All sounds a bit sinister and bizarre, right? Especially when Nick's own explanation about his decision to leave the X Factor totally contradicts this and says it was partly based around having curry with his mates!
Speaking on Radio 1, Nick told listeners: "It was one of those things. When I finished at Christmas and had time off and had a think about it and sat down, I just thought, it's one of those things I loved – it isn't a diss to the show or me storming out of X Factor like 'Screw you Cheryl!' It's a great show and I loved it but it's a once-in-a-lifetime style thing.
"And you can't have a curry when you're on it on a Saturday night because you're there. So what's really good about X Factor is watching it at your house with friends having curry. When you're there, there's no curry. And Simon promised me curry!"
Nick added: "I loved Simon and Cheryl and Rita and everyone who worked on it, and all the boys, the mentoring stuff, I loved. I just want to watch it on the telly."
A rep for X Factor has said: "Nick was a great mentor on last year's series. He did a fantastic job with the boys' category and we'd like to thank him for all his hard work. We are sad to see him go but wish him all the best."
