Bobbi Kristina's car accident

It looks like Bobbi Kristina and her brother-slash-boyfriend Nick Gordan have split up. After Bobbi Kristina posted several Tweets about broken hearts, Nick took to Twitter last to night to say, "Bobbi Kristina and I are not engaged or dating. Just close like we have always been."

Later, Whitney Houston's daughter, Bobbi Kristina, totaled her Camaro this afternoon (Wednesday) in a nasty-looking one-car accident outside Atlanta -- but she emerged from the wreckage with just bumps and bruises.

A witness called 911 to report a car crashed along an embankment, and when authorities responded, they found Bobbi standing next to the vehicle. She said she'd lost control while making a left turn outside her apartment building and rolled down the embankment, hitting some trees along the way.

TMZ says she received a traffic citation, but that the crash did not involve drugs or alcohol.
