Following Jonny's exit, Tyla was full of tears but quickly bounced back when she recoupled with Mike.
Tyla and Mike shared a kiss at the end of Friday night's show and Jonny hasn't been left impressed.
He told the Daily Star on Sunday newspaper: “I am pissed off. I’d be crazy if I wasn’t.
“I put her before myself in that situation and left so she could stay.
“But she hasn’t shown a lot of respect for me. I feel like she’s mugged me off. She’s let me down. I’ve lost a lot of respect for the girl.”
He went on to suggest: “She was acting so upset when I was leaving and then bang – I’m gone and she’s moved on. I think the crying was a little bit put on.
“Everyone does get quite emotional. But now we know how quickly she’s got over it, the tears just don’t look natural."
And Jonny teased: “If they put me back in now there would be fireworks.”
Jonny isn't the only one to question how genuine Tyla is with most recent evictee Theo Campbell also hitting out at her after his own exit on Friday night.
He told the Daily Mirror: "If she meant those tears she was crying, if she was really that upset about him leaving, then she should have left.
"I’ve seen straight through her and to me it was a bit of bulls***. I wanted to cut the tears out as I knew she wasn’t upset."
He added to the Daily Mirror newspaper: "I think Tyla is being a bit fake – definitely. She knows what she’s doing."
