Leonardo DiCaprio to Testify Against Slasher Aretha Wilson (PHOTOS)

In 2005 actor Leonardo DiCaprio was involved in an incident at a party where a guest, Aretha Wilson, slashed him in the face with a glass and then fled the country to avoid prosecution.  She has since been arrested and brought back to California to stand trial and her celebrity victim plans to be in the courtroom.

Last week the slasher, a 40-year-old ex model, was extradited from Canada back to the U.S.  She has been charged with assault with a deadly weapon and is currently being held on $150,000 bail.  Wilson made a brief appearance before a judge in court yesterday.

Clearly wanting to make sure that the slasher pays for what she did to him, DiCaprio will be in the courtroom when the case goes to trial and is willing to take the stand.

The actor was attacked five years ago at a Hollywood Hills party at the home of Rick Salomon.  DiCaprio received 17 stitches on his cheek and ear to repair the gaping facial wound.

Check out photos of Leo after having his face slashed and also a pic of the slasher:
