Colton has now spoken to the Daily Star about the subject, insisting that he was happy for Nu Vibe to mention his sexuality.
"I have never hidden my sexuality and I am proud of who I am. Nu Vibe are all my best mates," he is quoted as saying.
Colton revealed to Digital Spy that he was sick three times backstage last weekend.
"I vomited three times before I went on. I was filled with nerves," he said.
"Staff came backstage and saw me and were like, 'Should we call the paramedics?' I just laughed and said, 'No, you're alright, I've been sick now, there's nowt else that can happen!'"
