One-hit rap star Foxy Brown is in legal trouble for assault after bashing her neighbors head in with her Blackberry device.

The 27-year-old, whose real name is Inga Marchand, turned herself in to NYPD yesterday afternoon to be booked on felony assault, menacing, harassment and criminal possession of a weapon. She was arraigned and released on $5,000 bail.

Cops say the “Ill Na Na” rapper, who is currently on probation, smacked her 25-year-old neighbor on July 30 with her Blackberry during an argument.

The Crackberry truly is multi-functional.  I might have to look into getting one. Sounds hipper than brass knuckles.
