Californian Highway Patrol car had pulled Bieber's luxury car over for a routine check on Sepulveda Boulevard.
The photographer, who had been following the car, got out of his car to take several pictures while the police questioned the driver.
Bieber (18) was not in the vehicle at the time of the incident. One of his friends was driving the car while another friend was sitting in the passenger seat.
The photographer tried to take a series of photos while the police quizzed the driver and checked the car on Sunday.
But the paparazzo was advised by the Highway Patrol to move away from the Ferrari as the situation was unsafe.
As he made his way back to his own vehicle, the photographer was struck by an oncoming car.
James Stoughton of the LA police said that the photographer, who was not identified, was taking to Ronald Reagan UCLA Medical Center where he died shortly after.
Police have interviewed the motorist whose car hit the man, but it is unlikely that charges will be filed against him.
Bieber has yet to release a comment about the fatality.
No doubt Justin will be glad to see the back of 2012. In November, the Baby singer had a highway run-in with a paparazzo who claimed Bieber was driving too fast.
"What do your parents think about what you do? Do you tell them, 'I stalk people for a living'?" the singer asked.
The incident held up traffic in Hollywood. Before speeding off, Bieber said: "You guys love this, don't you?"
And last month, a gruesome plot to murder the Canadian crooner involving convict Dana Martin was alleged.
Mark Staake and his nephew, Tanner Ruane, were allegedly plotting to kidnap, torture, and kill the singer while he was in New York to perform at Madison Square Garden.
Martin had apparently ordered "the murder and castration" of the singer.
But Bieber seemed happy to ring in the new year, performing on Dick Clark's Rockin' New Year's Eve on Monday night.
