Kylie Jenner is being sued over a three-car pile-up she allegedly caused in August 2013.

The 17-year-old reality star was involved in a three-car pile-up in August 2013 - just 18 days after her 16th birthday - when the Mercedes G-Wagon she was driving allegedly slammed into the back of a Toyota which was stopped in traffic.

The second vehicle then rear-ended a Subaru and the woman in that third vehicle is now taking legal action, accusing the 'Keeping Up with the Kardashians' star of being a negligent driver.

Additionally, Kylie's mother Kris Jenner is also being sued over the crash because the driver believes the showbiz matriarch to be the owner of the Mercedes, TMZ reports.

The woman's attorney claims she suffered injuries to her back and neck in the accident. In August this year, Kylie was involved in another road accident when she reportedly made an illegal U-turn and smashed her $90,000 black Range Rover into an oncoming vehicle whilst driving through Katsuya in Glendale.

The other driver's lawyer also claimed the 17-year-old beauty was ''aggressive'' towards his client after the smash and even tried to persuade the alleged victim to not call the police in exchange for money.

However, Kylie reportedly told her parents immediately after the crash that a woman swerved into her lane and rear ended her. The teenage star is also believed to have received multiple traffic tickets since getting her licence just over a year ago.
