Ex On The Beach star and former CBB housemate Bear is one of the celebs apparently looking for love on this year's E4 series.
But Nadia, who alongside Eden sets up dates for the celebs, has not been impressed with his antics.
She claimed: "He preys on really vulnerable women. He tells them they’re beautiful and it’s the best date he’s ever been on.
“And he admits that that’s a lie. He’s said that. But what can you do?”
Speaking to The Sun newspaper, Nadia continued: "Bear is just a character, Bear doesn’t exist.
“Believe me, he should be thanking the people in the edit, because they edited him really well. It could be a hell of a lot worse for Stephen Bear."
And she added: “He doesn’t take the process seriously. He’s not interested."
In tonight's show, Nadia loses her rag with Bear after he makes a shock confession.
The celebs on this year's cast are gathered for a session with psychologist Judy James to discuss their dating experiences and feelings.
Bear makes a surprise admission as he reveals he may already have a girlfriend.
He explains cryptically: "There is one main girl I"m seeing outside the agency and we're having a very good time."
It's suggested that Bear's mystery woman is Geordie Shore star Charlotte Crosby, who herself appeared on Celebs Go Dating last year.
Watching on, dating agent Eden reacts: "He's got zero respect for us or any of our clients."
And Nadia fumes: "After this we're done we've got to do something about this."
Celebs Go Dating airs week nights on E4 at 10PM.
