Justin Bieber was driving in West Hollywood on Tuesday when he noticed paparazzi following and slammed on his brakes, causing a photographer's Prius to rear-end his red Ferrari, TMZ reported.
No one was hurt in the accident, but Bieber was certainly annoyed, tweeting, "We should have learned from the death of Princess Diana."
The 20-year-old star has gotten in trouble with the law repeatedly over the past year.
Bieber pleaded guilty less than two weeks ago for careless driving and resisting an officer in a January driving incident in Miami. The plea deal dismissed his driving under the influence charge and required him to take an anger management class and watch videos about tragic DUI cases.
