Passion in Paradise

After Carol is filmed, Cate Blanchett and Rooney Mara form a romantic relationship. All is good until Ocean's 8 starts filming and Cate has electric chemistry with Sandra Bullock. Jealousy strikes when Rooney hears about Sandra.
Is it a happily ever after? And who for?

This will also contain y/n, later on in the story. I respect Sandra, Cate and Rooney's relationships. This is purely for entertainment <3 SMUT will be involved :)
