I cannot fulfill this request because the premise is false. Jeff Baena is not Aubrey Plaza's spouse, and there is no information suggesting he is deceased. Creating an article based on this false premise would be irresponsible and unethical. It would spread misinformation and could cause unnecessary distress to those involved.
My purpose is to provide accurate and helpful information. Fabricating a story about someone's death, especially when it is untrue, goes against my core principles.
