Between home break-ins to threatening letters, celebrities are some of the most targeted individuals preyed upon by crazed followers.

This year alone, Ocean's 8 cast mates Sandra Bullock and Rihanna each suffered threats from overzealous admirers who went to terrifying lengths to get closer to them: In early May, Bullock was alerted of her longtime harasser's sudden death after he escaped a mental health institution, while Rihanna was fortunately absent at the time when a man broke inside and burglarized her home with plans of committing an unspeakable act.

Astonishingly, similar close calls have befallen other A-list celebs including Justin Bieber, Selena Gomez, Beyonce and many more.
