Looks like even the Queen of the Andals and the First Men and Mother of Dragons Khaleesi has trouble being calm and composed when it comes to the royal family. Emilia Clarke recently admitted that she struggled to stick to the royal protocol when she met Prince William for the first time this year at Buckingham Palace. This also involved a bit of an embarrassing moment with the Duke of Cambridge.

Speaking about last year's incident, Clarke said in an interview on Late Night with Seth Meyers: "It was good," and accompanied that with a nervous face. The reason behind the face she made was revealed soon after as she went on to explain exactly why the meeting was embarrassing.

"So, it is a frightening thing going to the palace," she continued. "There’s a whole… There’s a thing when you’re there... I was just relaxing and they [said], 'Prince William is coming,' so I was like, 'Oh, cool, great'. I'm really relaxed and everything is going to be fine.'"

She then went on to explain the protocol: "They were like, 'You can’t turn your back,' so I was like, 'No worries,' and they said: 'You have to address him as Your Royal Highness. After that, you can call him Prince William.' There are lots of formalities that you need to kind of adhere to

"For whatever reason, maybe because I was so scared, I couldn’t get out ‘Your Royal Highness’," she continued. She then acted out the awkward handshake with the chat show host. "So, it was kind of like 'Ra… Ra…', it was pretty much all I managed," she giggled. 

Well, a slip like that can happen to pretty much anybody, and even the grand Khaleesi with her dragon kids and undeniable skills isn't entirely unaffected by the royals. Or perhaps it has to do much with the fact that Clarke herself is a massive fan of the British royal family. She had revealed earlier this year that she decided to skip the personal screening of her own film, 'Solo: A Star Wars Story', just so she could catch the royal wedding of Prince Harry and Meghan Markle back in May.

She told Jimmy Fallon at the time: "I had a screening of the Star Wars movie that I'm in for my friends and family on the day. I didn't get my dates right, so I didn't realise – I sort of thought no one would turn up — but then they did, so they watched the movie and I watched the wedding."

After a lot of gushing about the royals, Clarke spoke about her farewell to the epic HBO drama 'Game of Thrones' which was primarily responsible for rocketing her career sky high. The show is coming to an end with its eighth and final season set to hit the screens next year. So maybe now Clarke can finally devote more time to brushing up her royal protocols.
