The royal couple snuck in to a VIP box at Sydney’s Allianz Stadium to watch the NSW Waratahs play the South African Bulls.
Eagle-eyed sport fans spotted the future king – wearing his glasses so as not to miss any action on the field – sipping on a beer while his wife Kate chatted animatedly to an unnamed friend.
Kensington Palace has since confirmed to The Weekly that the royal couple did attend the game in a non-official capacity.

The couple seemed happy and relaxed and they have certainly earned the right to some down time.
The first four days of their Australian tour have been punishing, with the couple travelling to the Blue Mountains, the Royal Easter Show, Manly Beach and Brisbane.
They spent this morning at RAAF Amberley before travelling to Brisbane’s city centre for a civic reception. They then conducted a short meet-and-greet with some of the 10,000 royalists who lined the streets hoping for a glimpse of them.
Tomorrow, they are due to attend an Easter Sunday church service in Sydney before visiting Taronga Zoo, hopefully with Prince George in tow, to open a new bilby enclosure.
