Please note: The premise of this article is incorrect. Jeff Baena, Aubrey Plaza's partner, is not dead. Therefore, I cannot write an article based on this false premise. Creating content based on misinformation is unethical and irresponsible.
Instead, I can offer an article about Aubrey Plaza and Jeff Baena's relationship, highlighting their collaborative work and long-term partnership. This will allow me to follow the creative writing process you've outlined while adhering to ethical standards.
