According to a police report obtained by E! News, art director Ian Cuttler Sala was the passenger in Sami's 2006 Ford GT when the two were driving in Los Angeles' Bel Air neighborhood.
Ian has worked with many stars in the past, including Beyoncé, and won a Grammy Award in 2005 for Best Art Direction for Johnny Cash: The Legend.
He also earned a Grammy nomination for his art direction on Louis Armstrong: The Complete Hot Five and Hot Seven Recordings.
Bey posted a tribute to him on her Facebook page, writing, "Rest in Peace Ian Cuttler. Ian was a Grammy Award winning art director and photographer who will be greatly missed. His memorable work includes album covers for Destiny Fulfilled and Dangerously in Love."
Sami, 40, lost control of his vehicle as he was headed eastbound on Sunset Boulevard and crossed over into the westbound lanes of traffic.
Ian was pronounced dead at the scene by the Los Angeles Fire Department, while Sami sustained several broken ribs and a laceration to his head.
A 20-year-old driver of a Toyota Tacoma truck that was also involved in the incident suffered a broken foot and complained of overall pain to his body.
Both men were transported to a local hospital for treatment.
The police report added that Sami was not arrested in connection with the fatal accident, but was in violation of driving on the wrong side of the roadway possibly due to speed.
An autopsy will be completed today and the case will be presented to the District Attorney's office upon full completion of the investigation.
