Think Mel Gibson's last rant was ugly? He may have topped himself. In 2006, the actor famously unleashed an anti-Semitic tirade during his DUI arrest a few years ago. Now the Lethal Weapon star may be in even more trouble after allegedly being taped while using the N-word and spewing a lot of other horrible things. "You're an embarrassment to me. You look like a f--king pig in heat and if you get raped by a pack of n---ers it will be your fault," Gibson is heard on tape, according to RadarOnline. Gibson's rep declined to comment on the latest rant, which reportedly comes courtesy of a recording made by baby mama Oksana Grigorieva during an ugly argument at the height of the couple's breakup and custody fight. If we were Mel's camp, we'd be keeping our mouths shut, too. Per the website, the star also called Oksana a "whore" and a "c--t," among other unsavory put-downs. "How dare you act like such a bitch when I have been so f--king nice," he is quoted at one point. "I am going to come and burn the f--king house down...but you will blow me first," goes another quote. The not-so-veiled threats are in addition to a slew of inflammatory emails the 54-year-old Gibson supposedly sent that the 40-year-old Russian musician has held on to, presumably for safe keeping in the event she needs them in a court of law. The Oscar winner is locked in a nasty court battle with Grigorieva, the mother of his nine-month-old daughter, over financial and custody arrangements in the wake of their separation back in April. Oksana has reportedly taken out a restraining order against him after she claimed he got "extremely violent" and punched her twice in the face. Gibson's lawyer described this exchange as a "loud argument." Gibson, as everyone remembers, made headlines for his notorious drunken outburst in which he yelled at Malibu's Finest after he was busted for driving under the influence in 2006, saying, "F--king Jews...Jews are responsible for all the wars in the world." Gibson's reputation and career took a major hit, especially in the wake of allegations of anti-Semitism in his 2004 blockbuster The Passion of the Christ. But after keeping a low profile and issuing several public apologies, people in Hollywood seemed to forgive and forget. But if this latest outburst is true, will they be able to forgive him again?
