According to gossip website TMZ.com, the couple had been arguing at the time of the crash - which destroyed the entire front end of the vehicle - and Nick's Camaro was the only car involved. No one was injured.
After the accident, the car was left without a front bumper and right front tyre, and the airbags were deployed, but it somehow got back to the couple's apartment.
Police visited the house soon after the accident following a noise complaint, but no one answered the door.

An incident report shows officers saw the vehicle parked outside the property with its hazard lights on, and it appeared to have been driven in a 'damaged state'.
The accident is currently under investigation.
Bobbi and Nick lived together as brother and sister for more than a decade before Whitney's death.
The chart-topping singer took Nick into her home at the age of 12 when his father went to prison and his mother was unable to take care of him.
Nick was the superstar's unofficially adopted son, and she treated him like family up until her death.
Whitney was found dead in a Beverly Hills hotel room on February 11, 2012.
The six-time Grammy award winning singer, died at the age of 48 due to an accidental drowning complicated by heart disease and cocaine use.
Nick first fueled rumours about a relationship with Bobbi Kristina in a tweet written in March, shortly after Houston died.
He wrote: 'Yea we got a little closer and what!!!'
The controversial couple have reportedly been sharing her $1.2million Atlanta home together ever since.
By the age of 30 Bobbi will have inherited everything that belonged to her iconic mother - mansions, jewellery, cars, and an extraordinary fortune.
