EXCLUSIVE

Grimes had a bizarre, unwanted visitor show up in her backyard — wearing a cape, no less — and now the man’s been ordered to stay away from her.

According to new legal docs … the singer and reported girlfriend of Elon Musk had an intruder at her home on July 10 named Raymond Barrajas. He allegedly scaled a hill at the back of her house while wearing a weird costume and carrying 3 computer mice.

The docs say he yelled out that he needed to see Grimes so he could “take her on a ride.” She wasn’t home, but her brother was and called 911. When cops arrived, Barrajas was still in the backyard and was yelling, “I’m a black man, shoot me.”

According to the docs … he was taken into custody and placed on a psychiatric hold. Grimes is worried the man has a delusional fixation on her and that he believes she is sending him messages through her music … so she went to court to get protection from him.

He’s now been ordered to stay 100 yards away from her, her brother, 2 friends and her pet.
