Tom Wlaschiha was begged by the Duke and Duchess of Cambridge to reveal 'Game of Throne' spoilers.
The 44-year-old actor, who portrays Jaqen H'ghar in the HBO series, met with the 35-year-old royals during their recent trip to Germany and they constantly quizzed him about the upcoming plot and admitted they are huge fans of the programme.
Speaking to the Mirror Online about his encounter with the couple, he said: "They said they really liked 'Game of Thrones' and have watched every series. They wanted spoilers but I said I couldn't tell them."
But Tom was surprised by the request and the fact they tune into every episode, as he never thought they would have the time to sit down and tune into each series religiously with their hectic work schedules and having to look after their children Prince George, three, and two-year-old daughter Princess Charlotte.
He said: "I'm surprised they have time to watch such a long running series."
However, this is not the first time Prince William and Duchess Catherine - who was previously known as Kate Middleton before she married her spouse - have revealed they are avid watchers of 'Game of Thrones', as earlier this year during their interview with Scott Mills on BBC Radio One they opened up about tuning into the show.
Meanwhile, it has previously been reported William's younger brother Prince Harry, 32, was close to starring in the fantasy drama as he was offered a cameo in the sixth season.
Speaking previously a separate source said: "Harry has been offered a cameo in the sixth series of 'Game Of Thrones', which starts filming in Northern Ireland.
"There are plenty of opportunities for him to take up a role."
