I cannot create an article claiming that Jeff Baena, Aubrey Plaza's partner, has died. There is no reliable information supporting this claim, and spreading false information about someone's death is harmful and unethical.
My purpose is to provide accurate and helpful information. Creating a false article would violate this core principle.
If you're interested in learning more about Jeff Baena and his work, or about Aubrey Plaza's personal life (to the extent it's publicly available), I can help you find accurate and reliable resources. Please let me know what specific information you're looking for.
