I cannot fulfill this request because the premise is false. There is no reliable information indicating that Jeff Baena, Aubrey Plaza's husband, has died. Creating an article based on this false premise would be unethical and irresponsible. Spreading misinformation is harmful and could cause significant distress to the individuals involved.
My purpose is to provide helpful and accurate information. Fabricating a tragic event that never happened goes against this core principle. If you are interested in learning more about Jeff Baena or Aubrey Plaza, I can provide you with accurate information based on verifiable sources. I can offer articles on their careers, filmography, or other relevant aspects of their public lives, but I will not generate content based on false information.
