The 911 call that R&B/hip-hop star Usher Raymond made to police reporting a trespasser at his home last month has been released, and in it the singer can be heard detailing how the trespasser was ringing his doorbell and sitting outside his front door.

In the call, obtained and posted by the website TMZ.com, the star, who goes by just his first name professionally, tells the female operator: "Ma'am, I don't know this woman. She rang my doorbell. … She's just sitting there."

He speaks softly, just above a whisper, and tells the operator that there are children and adults in the house.

"I think she's a little delusional," he said of the trespasser, telling the 911 operator that he didn't know how the woman gained access to his home because it was in a gated community.

He also says she appeared to be charging her iPad outside his house.

"I think she's a fan of some sort," he said.

He also explained that the woman had come to his home before, and she had been let in under the mistaken assumption that she knew someone there. Police were called to escort her away.

The suspect, Darshelle Jones-Rakestraw, was arrested, charged with trespassing and admitted to a hospital for psychiatric evaluation. She allegedly claimed she was Usher's wife, TMZ reported.

Jones-Rakestraw reportedly first came to the star's home on June 23, then returned a day later, when she was arrested.

Usher has reportedly obtained a restraining order against Jones-Rakestraw.

In a YouTube video posted Wednesday, Jones-Rakestraw said she was not a stalker and claimed Usher had defamed her character, TMZ reported.

She also claimed the star had been giving her money and had promised to help her music career.

In an interview with ABC News' Robin Roberts just days before the incident, Usher spoke of the pressures of raising his sons, Usher, 4, and Naviyd Ely, 3, who were both in the house the day Rakestraw was arrested.

"No one knows your children like you do," he said. "It is taking the time to actively be there. It's a day-in, day-out process."
