Bobbi Kristina Mysterious Tent Goes Up Outside Hospice

The hospice where Bobbi Kristina has been hanging on to life is preparing for something.

This is a photo of a tent that was just erected ... very possibly to prevent photogs from taking pics of something that is about to happen. The tent is flush against the back of the building.

As we reported, Bobbi Kristina's family is prepared to let her go, after doctors made it clear there was no real hope of recovery.

Bobbi Kristina has been at the facility for 3 weeks.
