LOL This reminds me of my Pearl. When Ziggy was still a kitten, I couldn't let her into my bedroom at night because she wanted to play all night so I only let in a few cats. Pearl was the main cat the loved to sleep in my bedroom at night and she claimed the bed as her own.
When I was able to let in all of my furkids again, she didn't like it very much and she would try to chase every one off of the bed especially Storm. She's finally gotten over it but it took a while. Yes, female cats sure can be diva's among other things.:)
