The British star has released a video of her son Harvey - who has been in Great Ormond Street Hospital in London undergoing a minor operation - in which he entertains his mother with the keyboard.

Katie, 37, captioned the adorable video: "My gorgeous boy entertaining me in hospital before bedtime #family."

The TV personality recently thanked her online followers for their supportive messages towards Harvey, who suffers from a rare genetic condition called Prader-Willi Syndrome.

Katie said: "Harvey is currently in Great Ormond Street Hospital for a routine operation.

"He will hopefully be out in a few days but I wanted to say how touched I am by all those asking about his wellbeing."

Katie also previously revealed she's grown used to dealing with Harvey's health issues.

She said: "I'm not going to lie - it's very hard work bringing up a child with disabilities ... He's on medication six times a day and if he doesn't take it, he'll die. And he has an injection at night.

"I can see how some people would probably find it hard because it's very challenging and stuff but I am a very patient and laid-back person and I think that makes a difference. I just love him and I wouldn't change anything about him."
