"Look out world! @kyliejenner is a licensed driver!" she wrote of her half-sister in an August 12 tweet.
It only took 18 days, but Kylie Jenner -- who celebrated her 16th birthday earlier this month -- started a three-car collision in Calabasas, Calif., on Wednesday.
According to TMZ, Jenner's Mercedes-Benz slammed into a Toyota, which then slammed into a Suburu. Jenner apparently got out of her car to apologize and exchange information with the other drivers. The Toyota sustained the most serious damage.
Jenner received the $125,000 G-Class car when she was still 15 and not yet legally allowed to drive. Her older sister, Kendall, previously received a $90,000 Range Rover as a 16th birthday present.
