This became even more prominent in the media when Jackson held the baby over the railings of the balcony of a hotel room in Berlin, four stories above ground.
The hotel incident took place when Blanket was only a few months old, and over time the nickname stuck.
Many of Michael’s children were similarly covered with blankets and other items to shield them from the press.
In terms of his parentage, Blanket was originally said to have been conceived by an anonymous surrogate, despite his older siblings, Paris and Prince, being the children of Jackson’s second wife, Debbie Rowe.
