TMZ has learned R&B sensation Brandy was involved in a fatal accident last month, and it appears to be her fault.

It happened at 10:30 AM on December 30, 2006 on the 405 Freeway in Los Angeles. Law enforcement sources tell TMZ Brandy was driving her 2007 Land Rover at 65 mph and did not notice that cars in front of her had slowed considerably. We’re told Brandy’s vehicle struck a 2005 Toyota. 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.

We’re told the driver of the 2005 Toyota was taken to Holy Cross Hospital in critical condition and she died.

Brandy was not injured. The driver of the Acura suffered moderate injuries.

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

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

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.

Statement from Brandy:
Brandy was involved in a car accident December 30, 2006 in Los Angeles where there was a fatality. She wishes to publicly express her condolences to the family of the deceased. Brandy asks that you respect the privacy of everyone involved at this time.
