The singer is the latest in a string of people to be victimized by someone calling 911 and falsely claiming there was violence occurring inside the celeb's house.   Law enforcement sources tell TMZ ... the caller claimed 4 black males entered the house and 2 shots were fired and they left a box with red blinking lights.

As we reported, it appears the hackers who obtained financial information from a number of celebrities, including Michelle Obama and Kim Kardashian, are behind the latest swatting incidents.
