Former Playboy Playmate Victoria Rathgeb appeared in a Los Angeles courtroom Friday and pled not guilty to attempted murder, RadarOnline.com has learned.

Dressed in an orange jumpsuit, the 66-year-old appeared stone faced as the plea was entered before Judge Barbara R. Johnson.

At a hearing last month, Rathgeb’s attorney requested to reduce the charge against his client -- also known as Angela Dorian and Victoria Vetri -- to assault with a deadly weapon.
