Katie Price has named and shamed a troll who slammed her as a "s**g" and blamed her for Harvey being overweight.
She posted a screenshot of a foul-mouthed reply to her story on Instagram , where one of her followers laid into Harvey, who is just 17.
Harvey is partially blind and has Prader Willis Syndrome which means he gains weight easily, as well as septo-optic dysplasia, which affects his growth.
He is also on the Autistic spectrum, and Katie recently explained that she had to make the tough decision to put him into part time residential care.
Appearing on This Morning, she told Eamonn Holmes and Ruth Langsford that she was struggling to deal with her much-loved son's behaviour.
"He's 6'2, 24 stone and still growing", she said.
"I adore him so much... but my house is smashed to bits, he's smashed eight iPads this year, four tellies."
And a nasty troll recently replied to one of Katie's Instagram stories with a vicious message about Harvey.
"Fat s**t Harvey he looks r******d! His fat cause of Katie she feeds him s**t", they wrote.
"This boy will always be fat and have a foul mouth all because of Katie. That slag!"
According to this person's profile, they are a health and social care nursing consultant.
Katie screenshotted and posted their profile, and in a video said: "If anybody knows this person or works with this person, I would question her job.
"This is exactly what she said about my son Harvey. Name and shame her."
MirrorOnline has reached out to a representative for Katie for comment.
Katie has worked with Harvey to raise awareness of his disabilities, and raised him mostly on her own as his father, Dwight Yorke, has not been involved in his life.
She has dealt with a lot of trolling against him, and had to delete his Instagram account after he was targeted by bullies.
In January, Katie's petition that the law needed changing to protect disabled people from hate-filled online abuse was approved by MPs.
A report found social media outlets must accept some responsibility for allowing "toxic environments to exist unchallenged".
Committee chair Helen Jones MP said: "The law on online abuse is not fit for purpose and it is truly shameful that disabled people have been forced off social media while their abusers face no consequences.
"There is no excuse for the continued failure to make online platforms as safe for disabled people. Self-regulation has failed disabled people and the law must change to ensure more lives are not destroyed."
