Billie Eilish has obtained a five-year civil harassment restraining order against an alleged stalker, 23-year-old John Matthews Hearle.

The 19-year-old artist alleges that Hearle harassed and threatened her with notes and gestures near her Los Angeles home for six months.

Eilish's protective order came following claims that Hearle has been camping out at a school across from her home.

The teenager also alleged that she has been bombarded with threatening and disturbing letters sent from Hearle, and claims he has even made a 'throat-slitting' move upon seeing her, according to legal documents obtained by TMZ last month.

The singer-songwriter claimed to have received one note from Hearle which read:

"You can't get what you want, unless what you want is to die for me ... You will know that soon the water will rise, and you might very well die ... You will die."

The singer alleged she has been watched entering and exiting her home by Hearle, who always makes some sort of gesture to her - including the throat-slitting motion.

In legal documents seen by The Blast, Eilish said Hearle's alleged activity causes her "emotional injury including fear for my safety, fear for the safety of my family, and loss of my sense of peace and tranquillity and security in my home and personal space resulting from the repeated instances of harassment".

She added, "I no longer feel safe going outside my home and enjoying basic physical exercise in my neighbourhood, as he could attempt to approach and hurt me...Every time I see him, I just want to scream."

Eilish also expressed that she becomes anxious every time she returns home with the knowledge of Hearle's presence.

The 'No Time To Die' singer also fears for the safety of herself, her mother Maggie Baird and her father, Patrick O'Connell.

She requested a court keep Hearle at least 200 yards away from her and her parents.

Eilish also stated he had been sleeping on school steps and perching himself at the top of the building's chainlink fence in order to look inside the privacy wall of her residence.

The alleged harassment has been occurring since August.

In May of last year, the pop star's family home was also blurred on Google Street View after she obtained a restraining order against a trespasser who visited her home seven times. She was granted the temporary order against 24-year-old Prenell Rosseau.

The talent's hugely popular Apple TV+ documentary, Billie Eilish: The World's A Little Blurry, was released last week to rave reviews.
