Even before Oksana Grigorieva caught Mel Gibson on tape in expletive-laced and racist recordings, he warned the Russian musician about his apparent rage-fuelled episodes.
As Oksana ramps up her legal case against the Oscar-winning actor/director, RadarOnline.com has exclusively learned Oksana has presented apparent evidence that the Lethal Weapon star had a history of acting violent and cruel.
As the couple's romance blossomed, Mel also eerily told Oksana: "I hope you never see my other side."
"Oksana said Mel had angry outbursts at least one or two times each month during the last year of their relationship," said a source, familiar with the case.
The abuse escalated in 2009, Oksana told investigators.
"Oksana said often these outbursts were precipitated by Mel's short fuse from trying to quit smoking or his uncontrollable jealously," said the source.
"She said his angry outbursts were completely irrational and set off by paranoia and jealously."
According to Oksana, Mel would "apologize profusely and tell her that he was 'mortified' by his behavior, yet days later, he would have another outburst."
