Mel Gibson's ex-girlfriend OKSANA GRIGORIEVA has testified under oath about her troubled relationship with the Hollywood actor as part of a bitter custody battle over their baby daughter.
The Braveheart star split from Grigorieva earlier this year (10) and the former couple is now embroiled in a battle over visitation rights to seven-month-old Lucia.
The Russian singer sat for the deposition in Los Angeles on Friday (02Jul10).
Gibson and Grigorieva's break-up has turned into a nasty legal spat in recent weeks with the musician reportedly winning a restraining order in Los Angeles against the movie star amid allegations he was violent towards her. Grigorieva has also accused Gibson of failing to pay for the upkeep of their child.
The deposition comes just a day after Gibson was accused of using offensive racial language in an expletive-laden, recorded argument with his ex.
The audio file has allegedly been obtained by, but the site has yet to go public with the recording and the actor has yet to confirm reports of the tape's existence.
