The son of Manchester United captain Wayne Rooney was caught signing autographs for supporters while his father's back was turned.
Five-year-old Kai was part of the United team's lap of honour at Old Trafford following the Red Devils' 1-1 draw with Arsenal on Sunday.
The youngster, who was wearing one of the club's away kits, joined his father and younger brother Klay, who scored a goal at the Stretford End during the post-match lap of honour.
Outside of the ground, one fan captured Kai on camera signing autographs for United supporters before Rooney grabbed his son's hand to lead him away.
Watch young Kai sign autographs in the video below:
