Junior, 14, took to Instagram today to tell his fans that he's suffering from COVID-19 symptoms.
The youngster remained claim as she updated his followers and said he is yet to be tested for the deadly bug.
He said: "I hope you are all well. These aren't easy times as we all know.
"I'm videoing this to let you know I am showing symptoms of the coronavirus.
"I'm not saying I have it, but I am showing symptoms.
"Everyone please stay safe. These aren't easy times as I said. God bless you all. We will get through this."
Junior's announcement comes after dad Peter appeared on Good Morning Britain to talk abut homeschooling his four children.
The Mysterious Girl hitmaker told GMB hosts Piers Morgan and Lorraine Kelly today that he is currently staying in a separate room to his doctor wife Emily MacDonagh.
Pete is looking after his four children Junior, 14, Princess, 12, Amelia, six, and Theo, three, while Emily is on the front lines for the NHS.
Speaking on Good Morning Britain today, the Mysterious Girl singer said: "Here's the thing, she obviously doesn't tell me a lot of stuff because of confidentiality.
"But obviously because she's now exposed to the virus quite a lot, at the moment, in the last few days, it means right now we are having to be in separate rooms.
"I am the one who has to have the kids as well and I'm terrified they will get it."
He added that his partner Emily is his "absolute hero" along with the other NHS staff.
Peter , who shares his youngest two children with Emily, recently expressed his pride on Instagram about his doctor wife.
He shared a photo of a group of NHS workers in a hospital, holding signs that read: "We stay here for you, please stay home for us".
Peter shared the snap to his Instagram Stories as well as his main page, adding the caption: "Proud :) #SupportTheNHS.
"Thank you so much to ALL the NHS and the carers up and down the country."
