For little Maisie Gregory it's a big moment. She's all dressed up and ready to meet the Queen!
The adorable little girl performs her part flawlessly, even giving a little curtsey at the end. The Queen starts to leave and it looks like it's all over. And then it happens!
You can see what exactly happens for yourself.
For me, the most amazing thing is that Maisie still performs like a trooper afterwards - even though everyone else ignores what has happened to her!
Take a look...
