Oksana Grigorieva will not be doing Oprah Winfrey's show, but contrary to a CNN report, it's not because the judge gagged her ... it's because one of her lawyers said, "No way."

There's a report out that Judge Scott Gordon ordered Oksana to pull the plug on "Oprah" ... we know that's simply not the case.

Judge Gordon did not order Oksana to stay clear of "Oprah." Period.
