Darshelle Jones-Rakestraw was arrested at the 'Scream' singer's Atlanta home on June 24, after trying to enter the house by telling police she was married to the performer.
Usher subsequently filed a restraining order against the 26-year-old, who maintained her innocence after the incident and alleges that the singer has been supporting her financially.
In documents obtained by TMZ, Jones-Rakestraw was in such an extreme mental state after her arrest that officers were forced to take her to a hospital instead of a jail.
Jones-Rakestraw was admitted to the Emory Johns Creek Hospital, where she underwent a mental health evaluation and was released shortly after.
She is expected to face the charges launched against her in court next month.
