Another commented: "She's so cute, and it's refreshing to see her so excited," while a third added: "Her excitement about staying in a real castle is infectious."
The coronation concert is set to take place on the East Lawn at Windsor Castle on Sunday 7 May at 8PM BST, so it makes sense to have the Firework singer staying on site – but what can Katy expect from her home for the weekend?
Firstly, the American Idol judge will have plenty of room. The 900-year-old property boasts around 1,000 rooms and 484,000 square feet of space.
While still a working palace, where Queen Elizabeth spent most of her time in her later years, there are lots of homely touches dotted around the castle, including paintings and framed photos of family members – perfect for Katy to peruse and brush up on her history!

Photos of the bedrooms at Windsor Castle are rare, so it remains to be seen what Katy's sleeping arrangements will be, though a photo of the King's bedchamber shared on Instagram suggests the bedrooms are rather opulent!
We can't wait to see Katy's posts from the event to see what living like a (pop) princess is really like.
