Another said: "TYLA IS A LIAR OMG!"
Director of vehicle services firm Andrew Georgiou claims to be the man in the explicit video, which shows sex acts being performed.
He said the whole thing was pre-planned as the girls had brought sex toys and paid for X-rated movies on the hotel room television.
Not that she or Muggy Mike probably care, though.
The then confessed he'd told Tyla he'd wait because he thought she wouldn't last in the villa much longer.
MailOnline has contacted representatives for Tyla for further comment.
It was also claimed that the three 'thoroughly enjoyed themselves'.
Instead of asking him questions about his fellow couples on the show, Piers chose to put Jonny on the spot and ask him general knowledge questions.
A source close to Tyla said she would "be furious about this" and 'if it is her, she'll be mortified'.
Fans watching the show took to social media to slam Piers for his "rude" presenting.
Last month, a clip of recent evictee Jess Shears, 24, "performing an explicit act" was given to X-rated website PornHub, but has since been deleted.
"The sex tape clip that has appeared online is about two hours into when we first started getting steamy".
As viewers will remember, Tyla was in floods of tears when Jonny left but as she's moved on so quickly, her fellow Islanders have been criticising her behaviour. If it is her then she'll be mortified that it has been leaked.
In her introduction video, she said: "My name is Tyla, I'm 23 and I'm from Surrey".
Chyna left the villa the week before Jonny exited, and previously called him the "biggest gameplayer", but she seems to have had a change of heart. I'd be insane if I wasn't.
One fan tweeted: "I think that Tyla is playing a MASSIVE game!"
'There were a lot of emotions going on when I was in there.
"I've seen straight through her and to me it was a bit of bulls***".
"Don't put feet near me, I'll throw up in the pool!" she added.
