*Aspiring porn actress Montana Fishburne, daughter of actor Laurence Fishburne, is “in a treatment facility and doing incredibly well,” her attorney Shawn Chapman Holley exclusively tells E! News.

Last month, Fishburne checked herself into a 30-day inpatient program for anger management and other behavioral issues in the wake of her latest arrest.

“I couldn’t be happier with her progress,” said Holley, who also represents Lindsay Lohan.

Having already pleaded not guilty to simple battery and false imprisonment for supposedly breaking into the home of her boyfriend’s ex, forcing the woman into the bathroom and repeatedly hitting her, Fishburne has also denied additional charges that were tacked on in August: assault with a deadly weapon and trespassing.

A pretrial hearing is scheduled for Nov. 16.
