Los Angeles 911 operators were flooded with calls in the minutes following Brandy's fatal car accident last month, as the R&B singer allegedly confessed she was at fault, according to TMZ.com.

"There's just been a massive car accident on the 405," one caller said.

"I think there's fatalities or injuries, big time," another said.

An unidentified witness told TMZ.com that the singer repeatedly said she was at fault for the fatal car accident on Interstate 405 on Dec. 30, 2006.

"She got upset, talking about how it was all her fault ... she didn't stop, kept saying how she hit the lady," the man said.

"Brandy walked in front of traffic, crossing the lanes of speeding cars, then she did it again," he told TMZ.com. "People were honking at her to get out of the road. She was obviously disoriented and highly upset."

On Wednesday, a publicist for the singer confirmed that Brandy was in the accident.

"She wishes to publicly express her condolences to the family of the deceased," said Courtney Barnes, her publicist, in a statement. "Brandy asks that you respect the privacy of everyone involved at this time."

Brandy, 27, was not arrested and she has not been charged with a crime.

The accident happened at 10:30 a.m. on Dec. 30, 2006. Brandy was driving her 2007 Land Rover at 65 mph and did not notice that cars in front of her had slowed considerably, law enforcement sources told TMZ.

Brandy's vehicle struck a 2005 Toyota, according to TMZ. The Toyota then hit a 1989 Toyota. The 2005 Toyota then slid sideways and hit the center divider. As the 2005 Toyota came to a halt, it was struck by a 1988 Acura.

The driver of the 2005 Toyota, Awatef Aboudihaj, was taken to Holy Cross Hospital in critical condition and she died the next day. Aboudihaj, a 38-year-old married mother of one, was a Los Angeles resident.

Police are doing a mechanical investigation of the cars involved in the accident to determine if there was a malfunction.

Brandy was not injured, and there is no evidence drugs or alcohol were involved.

The driver of the Acura suffered moderate injuries.

Brandy is best known for the TV show "Moesha," on which she appeared from 1996-2001.

Brandy's "Moesha" co-star, Lamont Bentley, was killed in January 2005 when his car plunged off the same freeway.

Another "Moesha" co-star, Merlin Santana, was killed by a gunshot wound while sitting in the passenger seat of a car in 2002.
