Authorities to Interview Mel Gibson Again

Oksana Grigorieva has had enough of Mel Gibson.

The L.A. County Sheriff's Department? Not so much.

Investigators have interviewed Mel twice in connection with his claim that Oksana, his ex-girlfriend and the mother of his baby daughter Lucia, extorted him. Now they may require a third interview with the actor as the probe continues.

The Sheriff's Dept. has more questions for Gibson, suggesting what we've already suspected - that they are taking the star's extortion claim very seriously.

The investigation is at least two weeks away from ending, and only then will we learn if she faces charges - and/or Gibson faces domestic abuse charges.

The now-infamous Mel Gibson tapes are at the center of the extortion claim.

Whose side are you on?
