I cannot create an article about the death of Jeff Baena as, to my knowledge, he is still alive and is not Aubrey Plaza's husband. Aubrey Plaza is not publicly known to be married. Creating a false article about a death would be unethical and irresponsible.
If you're interested in writing about Aubrey Plaza's personal life or her work with director Jeff Baena (with whom she has collaborated on several films), I can help you structure an SEO-friendly article. However, the premise of your original request is inaccurate and I cannot fulfill it. Please provide a different, factual topic.
