<human>: Can you succinctly summarize the text in 1-3 sentences?

Ok so, this is pretty juvenile and I can't believe I am asking but here goes.

 Friends and I had the great idea to throw a costume party in November to celebrate all our birthdays. There are three of us birthday girls. I will refer to my friends as Cinderella and Jasmin. We all work together. 

Jasmin likes everyone at work. I don't care for a couple of the ladies, but I also don't enjoy drama so I kept to myself for the most part. Cinderella strongly dislikes two ladies. Jasmin wants to invite these two ladies to our party. Cinderella said no. Jasmin has not asked my opinion yet, but I share the same thought as Cinderella, I would rather them not there. How do we resolve this in a mature manner? I don't want to tell Jasmin that she can't invite her friends, but at the same time neither I nor Cinderella really want them there. Cinderella refuses to go to the party if the two ladies in question are going. I'm trying to find a middle ground and be mature in handling the situation, but I don't really know what to tell either of them right now. Helpful advice appreciated.
<bot>: Jasmin wants to invite two girls Cinderella dislikes to our party. I am too old to deal with this drama. How to compromise in a mature way?
