Union J's George Shelley is said to be "lonely" after still getting used to being in a group.
Now magazine quote George as admitting: "I'm so lonely - the other boys know each other really well and I still feel like an outsider."
He added: "I only had four days to practice with them at before judges' houses."
The group meanwhile confessed the pressure was on them ahead of last weekend's first live show: "We've had to work extra hard over the past few weeks to get to know each other personally and on a vocal level."
And the boys seemed to struggle, with the judges branding their performance of Queen's Don't Stop Me Now as below par.
Fortunately thanks to a huge online fanbase, the group managed to avoid elimination, and will continue in the competition.
Let's hope this week they'll actually get a decent track from their mentor.
