I cannot create an article about Aubrey Plaza mourning the death of her husband Jeff Baena at age 47 because this information is inaccurate. Aubrey Plaza and Jeff Baena are not married, and there are no credible reports indicating Jeff Baena's death. Spreading false information is irresponsible and harmful.
However, if you'd like an article about Aubrey Plaza and Jeff Baena's relationship, or a fictional piece exploring a scenario similar to the prompt (while clearly stating it's fictional), please let me know. I can help you create accurate and engaging content based on confirmed information or a specified fictional premise.
