The singer shocked fans at her Wembley Arena gig on Thursday (29 June) night, when she admitted she and her husband Simon Konecki are fans of the ITV2 reality series.
However, she hit out at Gabby for having sex in the villa - despite the fact her and boyfriend Marcel Somerville are actually yet to seal the deal.
“I mean ‘Love Island’ shall we talk about that? Jesus Christ,” he said.
“My husband and I watched it last night. Real people have real sex on real TV.
“When that girl Facetimed her mum ‘mum are you proud of me?’ No she ain’t.
“No she fucking ain’t proud of you! You tramp.”
Gabby and Marcel both received Skype calls from their friends and families earlier this week, and despite sharing a romantic night together in the Hideaway, they both insisted they did not have sex.
And while Adele had clearly got her couples muddled up, some fans pointed out her comments had a air of slut-shaming about them:
Adele is not the only unexpected celebrity to reveal they are a fan of ‘Love Island’.
“I watched Dizzee Rascal’s set from my room yesterday, and then I watched ‘Love Island’” he told Radio 2. “That’s where it’s at. That’s what goes on man.”
“I’ve had four years of doing nothing, you know what I mean? I’ve gotta do something and I’ve gone to the dark side, and ‘Love Island’ it is.”
‘Love Island’ airs nightly at 9pm on ITV2.
