The woman who allegedly sliced up Leonardo DiCaprio's beautiful face back in 2005 was just arraigned in an L.A. courtroom -- where she pled not guilty to assault with a deadly weapon.
As we previously reported, Aretha Wilson is accused of attacking Leo with a drinking glass while at a house party in the Hollywood Hills -- causing 17 stitches worth of damage.
Wilson has been in custody since she was extradited back to the United States from Canada last month -- and is currently being held on $150,000 bail.
Wilson faces up to four years behind bars if convicted. Her next court date is August 23.
