Gemma Collins has had a complete body transformation, dropping three stone after overhauling her lifestyle.
But her mate Jonathan Cheban isn't buying her new look, saying her slimmed down figure "isn't her" because her "personality is to eat".
While he admitted Gem, 38, looks amazing, the reality TV star, 45, thinks she won't be able to keep the weight off.
He told The Sun Online: "In the pictures she looks beautiful. I hope she sticks with it.
"Her personality is to eat and have fun, so she’s probably dieting. It’s not really her. Like, Foodgod is me. With her, it’s eating and being fun.
"Maybe she's doing it for the health I know she loves to eat and enjoy it too."
Gemma kicked off her diet and fitness streak when she undertook gruelling rehearsals for Dancing On Ice.
She recently revealed her plans to go under the knife after her boobs went down in size because of her weight loss.
"I'd be really happy if I lost six stone as that would bring me down to 12 stone and a size 16," she recently announced.
"My boobs are so big and I want to get them reduced in January, but I have to lose three stone before they can operate.
"My boobs are 38GG now and I think I will go down to a C or a D-cup. The operation is all booked in.
"I think when you have big boobs, they can make you look bigger and I would just love to never ever wear a bra again."
It was recently revealed that there's more to her new figure than diet and exercise, with Gemma turning to SkinnyJab appetite-suppressing injections.
A three-week plan costs £250 with repeat injections priced at £135, and promises to reduce a patient's desire to eat in just three days.
Common side effects include feeling sick or being sick and diarrhoea and they're not recommended by doctors.
