The 39-year-old star was joined by wife, Victoria, at Hogwood Park on Sunday afternoon.
The famous couple’s sons, Romeo and Cruz, were both playing for Arsenal’s Academy sides against Royals’ youth teams.
They mingled with fellow spectators and parents while former England and Manchester United midfielder Beckham chatted with Reading’s first-team players.
Beckham also posed for pictures with several members of the Royals’ squad including Danny Williams, Hope Akpan and Oliver Norwood.
Spirits were already high at Hogwood following Reading’s 3-0 home victory over Fulham at Madejski Stadium on Saturday.
Reading host Millwall at Madejski Stadium tomorrow night (8pm ko).
