The woman who was arrested for breaking into and vandalizing the home of Chris Brown may have recently flown off the hinges ... living a delusion in which she believes she is Brown's wife.
Amira Kodcia Ayeb posted a message online 4 days ago, in which she says she's in Malibu "searching for her home." The 21-year-old from Tunisia also says her last name is Brown. It's apparent she thinks Chris is her husband, which is why she spray painted "Mrs. Brown" on his cars and in his house.
A friend of Ayeb's tells us Ayeb -- who is an aspiring singer -- attends the University of Houston, and she hopped on a bus last week and said she was going to see Chris. According to the University of Houston, Ayeb is not currently enrolled as a student.
TMZ broke the story ... Ayeb was arrested Wednesday night for breaking into Brown's home and vandalizing two of his cars. Chris found her naked in his bed, and it appears she was there for 2 days.
She is currently being held on $50,000 bail.
