The 23-year-old dancer made headlines earlier in the week when he said he would not rule out the possibility of a relationship with a man in the future.
After Curtis appeared on the ITV show on Thursday morning, viewers described Adil and co-host Kate Garraway’s line of questioning as “uncomfortable” and “disgusting”.
However, when Adil was challenged about the interview on Twitter, he stopped short of apologising, insisting he was just doing “his job”.
When Twitter user Jordan James asked Adil why he tried “force” Curtis to come out on live TV, Adil replied: “Because he talked about it in an interview and it’s my job.”
He later added that “it was great he was doing things on his terms.”
When another Twitter user accused co-host Kate Garraway of “badgering” Curtis, Adil insisted she hadn’t and that Curtis “loved it”.
During the GMB interview, Curtis insisted his sexuality was not something he felt the need to label, saying: “I think the future’s a road which is unwritten, nobody can ever say what’s going to happen in the future, really.
“I mean, last year, would I have said I’m on Love Island? No. This year, I was on Love Island. So, I never want to label what the future’s going to be, because I don’t think anyone can ever do that.
“So all I want to say is that I’m 100 per cent comfortable where I am now in my relationship with Maura and it’s moving in the correct direction.”
Explaining why he didn’t want to label himself as bisexual, Curtis explained: “Because I don’t feel like I need to label anything. Because, so many people put labels on things, people say things... and – I’ve learned this from the villa – my head’s not going to be turned – and then in the future... the head gets turned, they change their mind and opinion. Things change. That’s why I’m not labelling anything.”
