Katie Price has shared an emotional video in which her son Harvey asks people not to bully him.
The 17-year-old is partially blind, on the autistic spectrum and suffers from genetic condition Prader-Willi Syndrome, which can have an impact on development, leading to obesity, low muscle tone and learning difficulties.
In recent years, cruel trolls have targeted him online as a result of his disabilities.
The new video posted on Instagram shows Harvey holding up a poster from autism awareness organisation Anna Kennedy Online, which says: “Give us a break! Bullying is wrong. End of.”
Facing the camera, the teenager says: “Please don’t be horrible to Harvey.”
His mum is heard asking: “What don't you want them to do to other people?”
“Not be horrible to Harvey,” he repeats.
With prompting from Price, Harvey also urges others not to “be naughty” and not to “bully people”.
Price, 41, captioned the video: “My Harvey @officialmrharveyprice is my life nobody will ever break our bond.”
The star has often been outspoken about the abuse that her son has faced online.
She has pushed for the creation of Harvey’s Law, a measure to criminalise online trolling which she proposed to MPs during a trip to Parliament.
Price has said that tougher punishment for online trolls is a “no-brainer”.

And she has two children with her ex Kieran Hayler, five-year-old daughter Bunny and son Jett, who is six.
