More Trouble for Montana Fishburne

We don't know who struck first—Laurence Fishburne's daughter or the woman she's accused of beating up—but a court will sort it out

Montana Fishburne may be guilty of some questionable career choices, but when it comes to crime, she swears she's innocent.

Laurence Fishburne's porn-aspiring offspring pleaded not guilt today to two new charges stemming from accusations she beat up her boyfriend's ex: assault with a deadly weapon and trespassing.

Montana was MIA for the hearing. Instead, her attorney, Shawn Chapman Holley (who earlier in the morning was in Beverly Hills representing Lindsay Lohan) entered the plea in a Los Angeles courtroom after the city attorney's office filed an amended complaint.

Montana had already pleaded not guilty to the original charges of simple battery and false imprisonment resulting from the brouhaha, which went down last February.

According to the complaint, the 18-year-old allegedly broke into the home of the victim (whose identity has not been disclosed but was at onetime involved with Fishburne's current beau, Jerome Greene), forcing the woman into the bathroom and striking her repeatedly, causing "significant injuries."

No word exactly what weapon was used in the attack—or what daddy has to say about the whole affair.

In a separate case, Montana previously pleaded no contest in a Hollywood courtroom to criminal trespass and misdemeanor in a plea deal that saw prosecutors drop charges of solicitation and loitering in a public area for the purpose of prostitution. That stemmed from a bust back in November.

The next hearing in the assault case is scheduled for Sept. 28.
