Unconfirmed Internet rumors claim Britney Spears was arrested and charged with aggravated assault, assault with a deadly weapon and a misdemeanor drug charge late Monday night, after a 45-minute standoff with local police following an argument involving her mother and soon-to-be ex-husband Kevin Federline that resulted in Lynne Spears being hit over the head with a beer bottle.

Authorities received a call from Kev on Monday night claiming that Brit “viciously attacking her mother.”

When officials arrived at the scene, Brit was shouting several obscenities and waving around what appeared to be a broken beer bottle. Lynne Spears was rushed to the Hospital after Britney hit her with a beer bottle.

Sheriff Lee Baca said they also found “traces of cocaine” in Spears’ car. She was booked on several charges and is expected to be arraigned in Los Angeles County Court Tuesday morning.
