"My lad has asked me to get him and England kit with [Jamie] Vardy on the back," Rooney - who is dad to six-year-old Kai, two-year-old Klay and two-month-old Kit, - joked on ITV during England's game against Holland.
Luckily, the England captain had a few good words to say about Vardy, who plays for Leicester City and the England team.
"The impact [Vardy] has had on the Premier League is great for English football," Rooney added.
"Hopefully he can continue that."
Rooney didn't reveal which of his sons wanted the t-shirt, but it's likely to be his eldest who often joins him when watching football games.
In December 2015, the pair were seen during a father-son outing at an Everton football match.
The six-year-old has previously shown his love for football (and his dad) when he broke down in tears after watching Rooney dad lose to Uruguay in the World Cup 2014.
Rooney's wife Coleen gave birth to the couple's third child in January 2016.
"Our gorgeous little boy arrived today. Kit Joseph Rooney. 8Ib 1oz. We are over the moon," Rooney tweeted at the time.
