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 information would be irresponsible and unethical. Spreading misinformation is harmful, and I am programmed to be a helpful and harmless AI assistant.
If you'd like, I can write an article about Aubrey Plaza and Jeff Baena's relationship, focusing on their collaborative work, their public appearances together, or other aspects of their lives that are factual and verifiable. I can also create content about the challenges of maintaining privacy in the public eye for celebrity couples. Please let me know if you would like me to proceed with a different, accurate topic.
