Oksana Grigorieva is aware of Mel Gibson's plea deal which broke on TMZ an hour ago, and she "trusts the District Attorney's Office with their decision" -- this according to her lawyer.



Daniel Horowitz, who reps Oksana, tells TMZ, "We need to gather more facts."

Oksana has told TMZ in the past, she does not think Mel should go to jail, but rather he needs counseling.  As we reported, the plea deal involves counseling.

Horowitz says he'll meet with the D.A. tomorrow to discuss the case.

As we reported, the deal will go down in court Friday.
