Britney Spears caused a three car pileup on L.A’s Ventura Freeway on Saturday night.

The pop superstar and her Mercedes bump another motorist into heavy traffic while on the way home from an evening drive according to reports. The car she rear-ended hit the vehicle in front. No one was injured.

“Britney just appeared to lose concentration and drove into the car in front of her,” a witness told police.

“She failed to notice that the vehicle in front of her had come to a complete stop,” California Highway Patrol Officer Patrick Kimball says. “She attempted to break but failed to stop her vehicle prior to colliding with a 2006 Nissan.”
