The 33-year-old has obtained a temporary restraining order against 26-year-old Darshelle Jones-Rakestraw who showed up uninvited to his Georgia home on June 23 with the intention of harassing him and his family, reported TMZ Online.
According to court documents, Usher claims the girl showed up uninvited and started banging on his front door and demanded to be let in.
Cops were called to the scene where they warned Darshelle to stay away from the property and told her not to come back.
But the "OMG" hitmaker claims the girl returned again the next day and tried to convince the cops that she was his wife and had misplaced her keys.
The officials later arrested her and Usher immediately obtained a temporary restraining order against her. The singer is hoping to make that order more permanent during a hearing next month.
