Katie Price has shared her worries for her son Harvey as she revealed his current weight is becoming "life threatening".
Mum-of-five Katie, 44, posted a video of her son Harvey, 20, which shows her son sending her a message from the specialist college, National Star College in Cheltenham, which he attends.
In the clip, posted to Katie's Instagram profile on Friday, shows the teen wearing a pair of bunny ears on his head alongside a jungle patterned T-shirt.
He is stood behind a counter with a plate of chopped carrots placed on top.
In the video Harvey, who suffers from a number of health issues including blindness and Prader-Willi syndrome, tells the camera: "Hey everybody. I'm feeling healthy eating carrots."
Harvey then begins to pick up pieces of carrot from the plate and eat them.
The woman from behind the camera then encouragingly tells Harvey: "You're eating so healthy Harvey! Is it nice?"
He smiles and nods and continues to eat the carrots before the clip ends.
Proud mum Katie posted the clip on her Instagram story and gushed over her eldest son's latest achievement, but admitted her concerns over his weight.
As she shared the video on her Instagram, Katie penned in the caption: "I’m so proud of Harvey he has lost a stone now and his college are doing amazing trying to keep him active and healthy eating as it’s now become life threatening with his weight".
Mum-of-five Katie, who recently admitted Eurovision was her biggest career regret, then ended the caption with "#LoveMySon".
In December last year, Katie revealed Harvey had put the weight on that he had previously lost before heading to college.
At the time Harvey weighed 26 stone as Katie told OK! : "He did lose a bit of weight in the beginning when he first started, but now that he’s settled he’s putting it back on.
"Like I said about him smashing up his room, I think he feels very comfortable there now.
"He’s very clever and he knows what he does and doesn’t want – especially when it comes to food."
Harvey has Prader-Willi syndrome and, according to the NHS, those with the condition can become "dangerously overweight" if they are allowed to eat as much as they want.
The NHS adds: "Someone with the syndrome can eat much more than other people and still feel hungry."
Before moving him to college, Katie set Harvey up in his own home opposite her own pad to give him "his own space and independence".
Mum-of-five Katie told Loose Women how the move had also helped him lose weight as she said: "I really don't want to upset Harvey and you have to do transitions slowly, I want it to be fun for him.
"Now he's in the house opposite, obviously not on his own, and I've got cameras everywhere, he's on his iPad, and obviously I am there all the time as well, but it gives him his own space and independence.
"I think he's actually lost weight because when he's in the actual household, I've said before, he's quite disruptive in the night because he goes in the cupboards and eats the food - that's his Prader-Willi Syndrome.
"But in that house, I don't put anything in the cupboards that he can get, so he can't have a snack in the night because there's nothing there for him to snack on! I think he has lost weight."
