Katie Price was filled with pride as she watched her son Harvey's performance on his two-year-old brother's birthday.
Harvey, 13, who suffers from the rare genetic disorder Prader-Willi Syndrome, played the tune to Happy Birthday on the keyboard while singing along.
Two-year-old Jett tried chipping in himself pressing some high-pitched notes on the end of the keyboard.
The 37-year-old mum captioned the video on Instagram: "My gorgeous Harvey singing and Sting the keyboard singing happy birthday to my gorgeous birthday boy Jett!" followed by a long line of heart, love and celebratory emoticons.
Price, who is also mum to Junior, 10, Princess Tiaamii, eight, and one-year-old Bunny, later shared another sweet video showing her spending some quality time with her eldest son.
