After Breaking Celebrity News revealed Mel Gibson told his ex-girlfriend Oksana Grigorieva she "f--cking deserved" to get hit, the Los Angeles County Sheriff's Department has launched a domestic violence investigation after Oksana filed a complaint.

The investigation started on Monday when the victim made a complaint, L.A. County Sheriff spokesperson Steve Whitmore told Breaking Celebrity News. In the new tape recording, a teary Grigorieva can be heard asking the 54-year-old actor what he thinks he is doing hitting her while she is holding their eight-month-old child Lucia.

The allegations stem from a January incident at the actor’s Malibu mansion.

"What kind of man is that who would hit a woman while she is holding a child in her hands, hitting her twice in the face?” questions the Russian musician.

The Braveheart star answers: "You know what -- you f***ing deserved it."

Now the Sheriff's Dept. has confirmed its investigators are "currently gathering information regarding the allegations."
