However, the cute video sparked a backlash among some followers, with many thinking Katie was attracting trolls.
In the clip, the 14-year-old - who is autistic, blind and suffers from Prader-Willi Syndrome – danced shirtless and sang along to the Crazy Frog song.
Katie is heard asking: "Are you dancing Harv?", with her son replied: "Yes mum."
Pricey then prompts Harvey to sing along, with her and her friend Louise laughing in the background.
Harvey then says: "You are such a c*** Louise", with his mum chiming in: "Oi."
