Union J band member George Shelley hopes that singer James Arthur doesn't waste his talent.
Arthur, who faced a downfall in his career after making homophobic comments about a rapper, apologised publicly recently.
Shelley and other Union J members Jost Cuthbert, JJ Hamblett and Jaymi Hensley correct each other when any one of them goes wrong.
"We hope James is better soon. It's such a shame he's wasting his talent. His rampages were a bit of a shock to us after we became friends last year," said Shelley.
"As a band we have each other. If one of us speaks out of order, we have three others to slap us down," he added.
