Nope, we didn’t see this revelation coming either.
According to a new documentary ‘Our Queen’ which airs this Sunday, the royal couple can never bring themselves to finish a session of the word based board game because one of them will always ‘get in a mood’ before the end.
Olympic boxer Anthony Ogogo reveals the odd bone of contention between the couple during the documentary.
Kate told the boxer about her competitive nature last summer during a reception for Team GB.
Laughing, Anthony revealed: “She said when they play Scrabble they don’t usually finish a game because somebody got in a mood and slammed it shut.”
Well of all the things a couple could fight about, Scrabble isn’t going to cause much harm.
Perhaps the couple could benefit from a third party joining them to alleviate the tension though.
And we think we know just the man.
During his time with Taylor Swift, a source revealed that the couple had bonded over their numerous mutual interests including a love of the iconic board game.
They said: "They have loads in common and talk about music endlessly - Harry thinks Taylor's music is brilliant and has been asking for song writing tips."
"Plus, they both love scrabble!"
With Taylor now out the picture Harry must be on the lookout for a new Scrabble partner- but why have one when you can have two?
Now this is something we’d love to see.
