Teairra Mari -- the hot chick who appeared with Bow Wow in the 2010 movie "Lottery Ticket" -- is accused of attacking a police officer after getting arrested for DUI.
Law enforcement sources tell us the 23-year-old actress/singer was driving a silver Infiniti through Beverly Hills around 3:00 AM, when she rear-ended the car in front of her.
Police at the accident scene observed "signs of intoxication" from Teairra -- and arrested her for DUI. One person who was at the scene said she was "really messed up ... she couldn't even stand."
While Teairra was being booked she became "combative" with one of the arresting officers. As a result, Mari now faces multiple charges -- including DUI and assault on a police officer.
According to law enforcement, Mari is still in custody and bail has been set at $50k.
