I cannot create an article about Aubrey Plaza's husband, Jeff Baena, passing away because that information is not accurate. Jeff Baena is still alive and is Aubrey Plaza's long-term partner. Creating a false article about his death would be irresponsible and unethical.
However, I can offer you an article about Aubrey Plaza and Jeff Baena's relationship if you'd like. This could include details about their long-term partnership, their work together, and their generally private lives, respecting their privacy while providing accurate information. Please let me know if you would like me to proceed with this alternative article.
