Just 18 days after getting her license, 16-year-old Kylie Jenner was involved in a car crash yesterday, involving a 3-car chain reaction, TMZ reports.

Kylie was driving her brand new $125,000 Mercedes SUV through Calabasas around 5pm yesterday, when she slammed into the back of a Toyota, which slammed into the back of a Subaru SUV, according to TMZ.

Ironically, her older sister Kourtney Kardashian wrote on Twitter two weeks ago: "Look out world! @kyliejenner is a licensed driver!"

Kourtney Kardashian also proudly shared photos on Twitter of Kylie behind the wheel of her new Mercedes. Jenner has been driving for at least six months on a learner's permit, HNGN.com reports.

According to TMZ, the Toyota suffered major damage to the back-end of the car and the Subaru also suffered bumper damage.

A witness told TMZ that Kylie immediately got out of her car after the accident, apologized, and asked if everyone was OK.  She eventually exchanged information with the other drivers and left.

By the time the police arrived to the scene, Kylie was already gone.  

TMZ reports that no one suffered any serious injuries.

Kylie turned 16 on August 10, and was first spotted behind the wheel of the Mercedes at her Sweet 16 party on August 17, TMZ notes.

Jenner had an "Alice In Wonderland" themed birthday party at the AT&T Center in Los Angeles, with celebrities such as Willow, Naya Rivera, and rumored boyfriend Jaden Smith, IB Times reports. Surprise musical performances by Drake and Big Sean serenaded Kylie. Drake kissed her on the cheek and let her wear his gold chain.

"AHHH! Met my favorite people. Thank you all for such an amazing night. SOOO BLESSED xoxo," Jenner wrote on her Instagram account after the event, along with a picture of her and Drake, IB Times reports.
