Alex was one of four contestants dropped from the show during last week's shock dumping.
Speaking out after his exit, Alex has taken aim at some of his former fellow Islanders.
Picking up on Georgia's actions in the villa, Alex said: “Georgia has been to acting school and those lessons are paying for them for themselves.
"I’m not the only one who thinks it. Megan thinks it, Charlie does, Ellie does – which is why they had that fight, she’s just always acting up."
He explained: "If you get her for a normal conversation she thinks she’s fine, but if it’s a situation she thinks she can benefit from then she’ll act her way through it.
"She was heartbroken over Josh, but then there was the spat with Kaz, she kept getting her name wrong, just be the bigger person, don’t be bitter.”
In an interview with The Sun newspaper, Alex also claimed that some of the other couples currently together weren't genuine.
Alex suggested: “Frankie and Samira are together just out of convenience – well on Frankie’s side. Samira is really into him, but I just don’t think he feels the same, which is a shame as Samira is such a lovely girl who deserves to be happy.
“Jack and Laura aren’t genuine either, I think he’d be better suited with Georgia, I don’t think there’s anyone in the villa who’s a good match for Laura at the moment.”
But Jack and Dani are "the real deal", according to Alex.
"Their relationship is completely genuine," she said. "I don’t think they’ve ever even had a real argument."
