omg It can't be George although he is vocally the weakest one :S
maybe its Josh? But Josh has a great voice so....idk out of all of them Josh seemed like he was most likely to leave the band. he looked so un enthusiastic about it all by the end of their 2nd era tbh.
George was apparently offered a role in one of the UK's largest soap operas so maybe it's true and he accepted the offer.
I'm happy for George. Nobody is here for Union J anyway: their last album charted at number 28 lol and they've never had a certified single. If they actually get around to releasing a third album, with or without George, I'm sure they will be dropped after it.
Jaymi can sing (amazingly), so that rules him out; and Josh is the only one who ever tweets about his excitement for their next era (the last time he tweeted about it was on New Year), as well as still use the group account; and she definitely wasn't talking about JJ.
It must be George considering he's the only other one who can't really sing in the group.
That said, JJ's girlfriend shouldn't say this though, JJ is literally the most untalented band member ever.
