Oksana Grigorieva to launch the offensive

With the help of her new lawyers, Martin Garbus and Daniel Horowitz, Oksana will file a lawsuit against Mel Gibson, the father of Lucia, for all of the above.

Garbus and Horowitz will serve her reps in connection with the domestic violence investigation against Gibson and the extortion probe against Oksana.

Moreover, they will also argue that Gibson is unlawfully blocking the release of her music.

As for the civil battery case against Gibson, who Oksana says hit her in the face and threatened her life, sources say the plan is to file it by the end of 2010.

An additional aid is given by Violet Kowal who also says she has tapes of her own to prove that she was railing Mel while Oksana was pregnant.
