Brown was not injured in the crash, which occurred around noon in Los Angeles, but some reports say the car was totaled.
The incident is under investigation, but Brown told police he lost control of the car while he was trying to get away from photographers, according to the AP.
The crash happened a day before Sunday's Grammy Awards, which Brown is scheduled to attend as a nominee for Best Urban Contemporary Album.
Last month, an amateur photographer was killed as he was trying to take pictures of Justin Bieber's car.
