What are your thoughts on yet another outburst from Mel?

Mel Gibson is caught on tape, screaming at his baby mama Oksana Grigorieva, "You look like a f*king pig in heat and if you get raped by a pack of ni**ers it will be your fault." The tapes were secretly recorded by Oksana in the midst of their nuclear breakup and custody battle. 

We've also confirmed Mel is heard on tape calling Oksana a "whore" and a "c**t."

The tapes have been submitted to the judge in their custody battle and are under seal.  Sources say the tapes were recorded prior to May, when Mel and Oksana reached a custody agreement with a mediator.

Oksana Grigorieva went to her lawyer's office today ... before the judge called the attorneys on both sides into court for a closed hearing. The judge wants to know who leaked the tapes.  News reportors have learned ... if the judge traces the leaked Mel Gibson tapes to Oksana ... it could have an impact on her rights with respect to the custody order -- an order that has financial ramifications.

Oksana was prohibited under a restraining order from releasing the tapes or otherwise disseminating the information.
