SERIAL cheat Stephen Bear has split from his latest girlfriend Georgia Harrison amid fears he has been unfaithful again — and has already moved on to a Next Top Model wannabe.

The love rat started dating the former Love Island star whilst they were filming The Challenge for MTV in the US.

But it is all over after he did “something to her” which she fears means he has cheated again.

A source said: “It was over before it even began.

“He’s done ‘something’ to her but he won’t tell her.

“Given his history it’s pretty safe to assume he’s done the dirty again.”

He is now seeing Poppy Gibbs who made a desperate plea to go on TV show Britain’s Next Top Model by uploading a cringe video.

It comes after he cheated on girlfriend Ellie O’Donnell with former Towie star Georgia in America.

The Sun revealed last month how Stephen then dumped his model missus over FaceTime.

A source said at the time: “It was quite recent. After that happened he finished with Ellie over FaceTime.

"Now he and Georgia are seeing each other. They're an item. Ellie is fuming.

“Filming for the show is supposed to be secret and they’re pretending like they’re still in the UK.”

They added: “He thinks dating Georgia, because she’s a bit of a name, will boost his career.”

Georgia previously hinted she’d split from him earlier this month after he danced with other girls in Instagram videos.

Women were seen grinding on the ex-Celebrity Big Brother champ in the raunchy clip and Georgia, 23, failed to hide her sadness when she broke her silence online today.

Stephen, 28, invited two women back to his hotel room whilst on holiday in Los Angeles, after he dined in posh restaurant Nobu.

Georgia tweeted: "A leopard never changes its spots."
