Well, create a few templates like some online media currently use and let bots fill the info in. The content should not change much from event to event.
I think that celebrity gossip articles would be prove to be as ritualized and standardized as sports and stock market articles; places where algorithmic article generation has worked well. You'd probably only have to hire human writers to do longform features and interviews, and to create an underlying model to generate the activity of these fake celebrities that you would be reporting on.
