Mel Gibson allegedly unleashes another foul-mouthed tirade against his ex-girlfriend and claims he is broke in a new recording realised online. The 54-year-old actor is currently being investigated over an alleged domestic violence incident involving his ex-girlfriend Oksana Grigorieva. Mel went public with his relationship with the Russian singer just one month after his wife of nearly 30 years Robyn filed for divorce last year. Oksana gave birth to the couple`s first daughter Lucia, in October, but they split in April this year. Their relationship has become increasingly acrimonious in recent months, with Oksana taking out a restraining order against Mel after he allegedly became violent with her. In return, Mel filed for custody of Lucia. RadarOnline has posted a series of recordings in which they claim Mel uses racist and other offensive language while arguing with Oksana. In the latest tape, a man purported to be Mel calls Oksana a series of degrading names and claims he has no money. "B***h, ****, w***e, gold digger," the man screams. "I don`t have any f**king money! F**kin` user! You f**kin` used me! I will never forgive you. I will never forgive you for what you`ve done to me you f**king bitch! When the woman said to be Oksana accuses him of ruining her life, he screams: "You ruined MY life first! I ruined your life? How did I ruin your life? I gave you sh*t! You gave me nothing but f**king grief! Alright? And bad publicity, you ****! How did I ruin your life?" Mel can then apparently be heard panting and puffing for several seconds, and appears to be struggling to breathe. The woman alleged to be Oksana - who has a 12-year-old son with actor Timothy Dalton - eventually accuses him of being "mean", sending the man into a tailspin. "Yeah, you know what mean is now, don`t you? So don`t call me mean when I`m nice to you. Because I`d like to show you what mean really is. B***h, ****, w***e, gold digger! All true!" he yells. "You f**king proved it to me! If you`re ever interested in proving otherwise, let me know. If you don`t care, I know you know what you are too. "Look at yourself. And look what you`ve done. Look what you`ve f**king done! Look at your son. He`s a f**king mess. You f**king excuse for a mother. You`re a f**king b***h!" Mel then allegedly says he is so short of cash he has started selling some of his precious artworks, and no longer goes to see the Los Angeles Lakers play basketball. "I don`t have any f**king money! I have to support you and everybody else!" the man says. "I spent too much goddamn money on you! And my wife knows! It`s you!" Oksana has told police Mel knocked out her two front teeth during an argument in Malibu on January 6. It is then alleged Mel waved a handgun in her face, saying: "I will show you how to get out of here first." Oksana`s lawyers are said to be going to court today to ask a judge to ban Mel from seeing Lucia. According to TMZ, the tapes will be used as evidence the Hollywood star is a danger to the baby. However, the recordings still need to be authenticated by authorities. Mel has denied hitting Oksana. Website TMZ reports his lawyers believe they have evidence the tapes were tampered with. If that is found to be the case, they would be inadmissible in court.
