Last year, viewers of The X Factor saw Nick and Rita Ora flank Simon Cowell and Cheryl Fernandez-Versini on the show, but after just one series Grimmy decided to step down.
Josh was mentored by the Radio 1 DJ on the show, but despite being sorry to see him go so soon, the aspiring singer revealed he expected the judging panel to change.
Opening up to Reveal recently about the X Factor's new series, Josh exclusively told us: "Yeah of course [I was sad to hear Nick left.] When we were on the show, all of the lads were really close to Nick."
Gushing about his old mentor, the 22 -year-old continued: "He was a really great guy and he devoted a lot of his time to helping us out. We still chat now and then.
"It was a shame he had left the panel, but, at the same time, The X Factor likes to change it up. It was probably likely that some of the judging panel would change."
News broke that Nick had decided to leave The X Factor in February, earlier this year. Grimmy had dubbed the show as a "once in a lifetime experience", joking that he wanted to go back to watching it on the tele.
Despite revealing he had kept his decision to leave a secret from Rita and Cheryl, Nick insisted there was no "bad blood" between him and the other judges. He said: "I loved Simon and Cheryl and Rita and everyone who worked on it, and all the boys, the mentoring stuff, I loved. I genuinely loved it. There is no bad blood. I just want to watch it on the telly."
He's not the only judge to quit, as Cheryl recently confirmed she has decided to leave too. So far, their replacements on the panel are still yet to be confirmed, but reports have claimed it's 'almost certain' Louis Walsh could find himself sitting back alongside Simon.
On the show last year, Josh sailed through to Judges' Houses after wowing the panel with his audition of Labrinth's 'Jealous' and Nick at the Six Chair Challenge. Many had thought he would have been a dead cert for the live finals, but Grimmy failed to put him through - choosing Che Chesterman, Mason Noise and Seann Miley Moore.
Looking back on his time on the show, Josh assured us he isn't holding Grimmy's decision against him.
He said: "I'm a firm believer that everything happens for a reason. When I didn't go through on the show, I didn't beat myself up too much. I had achieved so much at that point through the show, that I was too grateful to be bitter about it."
"I feel everything has worked out the right way," he added.
Since the show, Josh has flown to America to work with Jay Z's label Roc Nation on his debut album. Before treating us to his own material, though, Josh has recently released the full version to his rendition of 'Jealous' after being inundated with requests from fans.
Josh's full version of 'Jealous' is now available to stream and download now on iTunes and Spotify.
