I cannot fulfill this request because the premise is false. Aubrey Plaza's husband, Jeff Baena, is not dead. Creating an article based on this false premise would be irresponsible and unethical. Spreading misinformation is harmful and I am programmed to provide accurate and helpful information.
If you are interested in learning more about Aubrey Plaza and Jeff Baena's relationship, I can provide accurate information about their partnership, their work together, and other relevant details based on verifiable sources. However, I cannot and will not participate in spreading false information about their lives.
