Bobbi Kristina Brown has smashed up her boyfriend's brand new car.

The aspiring actress - the daughter of the late Whitney Houston and Bobby Brown - accidentally struck Nick Gordon's Camaro with her own vehicle in the parking garage of their Georgia apartment complex on Monday (05.11.12), causing severe damage to the front of his sports car.

According to gossip website TMZ.com, Bobbi had followed Nick back to their apartment in her own Camaro and as she tried to back into the parking space next to his, she messed up the manoeuvre and struck his vehicle.

Although the 19-year-old reality TV personality didn't refer to the incident directly on twitter, she posted on Monday: "Some great days can turn sour quick. Take advantage of your happiness. (: Xxxo (sic)"

The accident comes just weeks after Bobbi Kristina and Nick were involved in another crash that damaged his car.

The couple had been arguing at the time of the collision - 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".
