X Factor's Union J are back to four members, thanks to one of Stereo Kicks.
Union J, who made the live Quarter Finals of The X Factor back in 2012, partially split in March this year after George Shelley left the group.
It undid the work of The X Factor judges who originally put the group together on the show, having added then solo singer George to trio Triple J - made up of Josh Cuthbert, JJ Hamblett and Jaymi Hemsley - to form Union J.
Now The Sun newspaper reports (via Digital Spy) that Stereo Kicks' Casey Johnson will be replacing George.
Casey was one of EIGHT members of Stereo Kicks who appeared on The X Factor in 2014, splitting last year.
"I have always wanted to be in a band, not a choir," Casey said "What I was in before wasn't like a boyband. Stereo Kicks was more of a choir."
He added: "Union J were always a much bigger band than Stereo Kicks. These guys are more mature and I feel already that this is the type of music I want to do."
Speaking earlier this year, Union J's Josh told The Sun newspaper of George's exit: “I wrote a really strong email. We basically gave him an ultimatum. It was, ‘You’re either in the band or you’re not’. George was in a position where he did the jungle, he came off it and his head space was different to ours.
“Using a sporting analogy, he wanted to turn up to the big matches but not turn up to training.”
He added: “I would much rather have someone who wants to do it and is committed to do it. I’m not going to lose any sleep over him not being in the band.”
However Jaymi said he was "devastated" by the split and described it as "heart-breaking."
He confessed: “I am bitter about things that have happened. He wasn’t putting his the full effort in. One member is not bigger than the band and we feel that there should be no member who is bigger than the project.”
In response to the comments, a spokesperson for George hit back, saying that the split was mutual and that the rest of the group were just "jealous".
"George left Union J as he had been offered a two year contract with Capital Radio and a contract with the BBC," they explained at the time. "He wants to focus now on broadcasting. He is beyond charming and not a diva at all.
"The other members of Union J are simply jealous he has achieved the start of a new career and they have not.
"George had agreed to be totally magnanimous towards them."
