I cannot write an article about the passing of Jeff Baena, Aubrey Plaza's husband, because, to my knowledge, Jeff Baena is still alive and is not Aubrey Plaza's husband. Aubrey Plaza and Jeff Baena have been in a long-term relationship, but they are not married. Reporting on a death that hasn't happened would be irresponsible and harmful.
However, I can offer you an article about the relationship between Aubrey Plaza and Jeff Baena, highlighting their successful collaboration and long-lasting partnership, if that would be of interest. This would allow me to follow all the steps you outlined in your prompt, but in a factual and ethical manner. Please let me know if you'd like me to proceed with this alternative topic.
