Right after the Brown Eyed Girls performance on Music Bank, the girls were headed to another scheduled event near the Han River at around 8pm, when they slightly collided with the car in front of them. The car in front of them stalled because of a flat tire and the vehicle in which the Brown Eyed Girls were in slightly collided with the car in front. The members didn't have any injuries of note, but some were reportedly a bit shocked about the whole ordeal. They changed vehicles and continued onto their next schedule.
Luckily no one was hurt, just the other day SNSD got in a minor accident as well, hopefully everyone drives more carefully.
