Coleen Rooney has shared an adorable picture of her son Kai holding hands with his younger brother on his first day back at school.

"Back to school for Kai!" she wrote on Instagram, with the picture of five-year-old Kai - in full school uniform - alongside his brother Klay, two, who was dressed in a Manchester United kit.

Next year, Kai could well be pictured with another little brother or sister after Wayne and Coleen announced in July that they were expecting their third child in the New Year.

"It’s exciting for the boys not to know whether they’ll be having a little brother or sister," Coleen, 29, told OK! Magazine recently.
