Rooney's four-year-old was photographed wearing football shirts while spending time with his father in Portugal last week at England's pre-World Cup training camp.
However, Coleen has revealed that the youngster is yet to take a huge interest in the sport.
"Kai isn't much into sports at the moment, but he is always running around and likes to try new things," Coleen told Cheshire Life magazine. "I know Wayne is looking to spot a few football skills in him, but at the moment he's mainly into dancing."
The couple are also parents to son Klay, who was born in May last year.
