Glamour model Jordan's son is in a specialist burns unit after an accident on New Year's Eve.
Jordan, real name Katie Price, is at her son's side in hospital
Harvey, four, was taken to hospital by ambulance hours before Jordan and her husband Peter Andre were due to hold a New Year party at their Surrey home.
He is now at London's Chelsea and Westminster Hospital in a stable condition, Jordan's agent said.
Claire Powell said the couple were with Harvey constantly and were "being strong for him".
Ms Powell said: "Harvey is now in a stable condition, but that's all I know.
"I haven't spoken to Pete or Katie because they're at the hospital with him constantly.
"They're with him 24-7 and their phones are off. I don't know how it happened, but I got a text from them to say that he's in a stable condition.
"They are devastated, but they are being strong for Harvey."
The couple have now cancelled their holiday to Australia which was due to begin on Tuesday.
Harvey, who has a growth disorder and is partially blind, is the son of footballer Dwight Yorke.
Jordan, 28, whose real name is Katie Price, is currently pregnant with her third child.
