The Prince of Wales admitted he has had to put up with "non-stop" grief since Wales lost to England in the latest round of the Six Nations.
The Prince, a big fan of the Welsh rugby side, was in the stands at the Principality Stadium on Saturday, sitting next to his wife as she cheered on Steve Borthwick's team to victory.
And during a return trip to Wales on the eve of St David's Day, he admitted that the 20-10 beating had been difficult to take.
The 40-year-old has been patron of the Welsh Rugby Union since 2016, while Kate is patron of Rugby Football Union (RFU) and Rugby Football League (RFL), after taking on the role from the Duke of Sussex a year ago.
Three days on, and the Prince still finds it difficult to talk about the game. Follow their visit to Wales live here.
During the visit to Brynawel Rehabilitation Centre near Pontyclun on Tuesday, William was asked several times about the rugby match they attended on Saturday.
Asked if he enjoyed the game, the Prince of Wales joked: "Not really."
He later told volunteers: "I've had non-stop grief about it all weekend."
Wales lost their third Six Nations match in a row under Warren Gatland and next face Italy in Rome for a likely wooden spoon decider.
