The way this works is that first, someone will name a character and then a person will respond with a celebrity they think looks like the character and they get to decide the next character and it continues. It doesn't have to be limited to just the Disney Princesses, you can do the princes, the villains, the human sidekicks, the human side characters, or whoever. Heck, you can even use human characters that are Disney in general, not just the Disney Princess characters. But they have to be humans because if someone chooses an animal, they'll add someone like Percy and just pick a celebrity they hate to bash them. So it can be any character, as long as it's human or human looking (meaning characters like Ariel, Triton, Athena, and Ariel's Sisters). Here's an example on how this will work.

A: Cinderella.
B: Lily James
Mad Madam Min
C: Kelly Osbourne
Aurora
D: Audrey Hepburn
Esmeralda

And so forth. Feel free to use pictures.

Let's start with Snow White
