Kate starred in the production while attending St Andrew's Preparatory School in Buckhold.
Jodie said his nan was so excited to hear Kate was coming to the school she nearly cried, and he told the duchess: "I'll tell her you said hi".
"It is all I've ever hoped for!"
At the event she opened up about the impending birth, joking that her husband, Prince William, is "in denial".
But it turns out the Duchess of Cambridge's life story has another classic element of any good fairy tale: a fortune teller predicting all the happiness to come. The Duchess of Cambridge is under scrutiny, with tabloids and internet trolls calling her hands "very unusual", because almost all of her 10 fingers might be the same length.
"I was like 'what is she going to say?' And I was practising for everything", she said. Later this year she also has another exciting wedding - Princess Eugenie will be marrying long term love Jack Brooksbank, also at Windsor Castle, on 12 October.
"Soon you will meet a handsome man, a rich gentleman", the fortune teller tells her.
Similar to her school play, Middleton did say yes, but this time, to her real prince.
In the next scene, Kate appears with a prince, who gets down on one knee and proposes marriage to her.
Ten-year-old Zhara Gathenya who had the honour of meeting Her Royal Highness along with a handful of other children her age was quoted in saying, "It's probably a once in a lifetime opportunity to actually meet somebody from the royal family..."
Years later, on April 29, 2011, Kate walked down the aisle with Prince William.
