Jason Gardiner has blasted Gemma Collins as "lazy" and "mediocre".
The 'Dancing On Ice' judge hit out at contestant Gemma, claiming she is not working hard on the show and blasting her for her overconfidence in her own abilities.
He told The Sun: "I can always see who's lazy. Gemma is lazy. She doesn't look like her heart is in it at all.
"I've never seen the show Gemma is from. I don't watch a lot of these types of shows, I'm too busy and life is too short. So I wasn't aware of this phenomenon that is Gemma Collins.
"But I had heard the hype from her own mouth, how amazing she is and how she's better than Beyoncé.
"I was so excited. But then she came out and did what can only be described as one of the most painful routines I've ever had to sit through because it looked so uncomfortable.
"I kept worrying that she was going to fall over and hurt herself. That was a genuine worry."
Jason also labelled Gemma "insecure" and urged her to stop complaining and start rehearsing as he worries she is a bad role model for young people.
Earlier this week, Gemma threatened to quit 'Dancing on Ice' after presenter Holly Willoughby questioned her "professionalism".
The 37-year-old reality TV star was said to be hurt after Holly, 37, accused her of displaying a lack of "pride" in her work by leaving the hit ITV show 15 minutes early on Sunday night (13.01.19).
A source said: "Gemma's a nightmare but is getting away with it because producers know she's the biggest draw.
"On the first show she told an exec she was the star so shouldn't have to be in group performances or stand on the balcony to watch the others.
"On social media she makes out she's pals with them but in reality she doesn't care.
"She's devastated by everything that's been said about her and is threatening to quit."
Dancing on Ice's digital presenter Kem Cetinay claimed on Monday (14.01.19) that the 'The Only Way is Essex' star left the live broadcast before the end because she was a "bit bored".
He said: "We went into the live show, and then the last quarter of the show, she went home.
"Well I didn't know she went until after but then we saw this video and I was thinking, 'I don't know where Gemma is?'
"I went to her dressing room and she wasn't there. So I did speak to her after and she said she was a bit bored, but she does love skating."
Holly then gave her opinion on Gemma, saying: "The thing is I really love Gemma, you know I'm a big fan of Gemma's and I think she's great on the show. I do, but I think there has to be a bit of professionalism that comes into any work you do, just a bit of pride in your work."
