London, (ANI): Mad Max star Mel Gibson"s ex-girlfriend Oksana Grigorieva is set to reveal all in a candid chat with talk show queen Oprah Winfrey.
Gibson, 54, has seen his private life played out in the press since splitting from Grigorieva earlier this year, with the Russian singer accusing her ex of beating her and knocking out her teeth during an argument in January.
Taped disputes between the pair have since leaked online, in which a man thought to be Gibson could be heard admitting to the attack before launching into an expletive-laden rant, the Daily Express reported.
According to Us magazine, police are currently investigating the domestic abuse claims but Grigorieva will open up about the troubled relationship in an upcoming TV interview on The Oprah Winfrey Show. Executives at Winfrey"s production company Harpo reportedly beat producers from U.S. programme 60 Minutes to land the Grigorieva exclusive.
