We can't remember the last time a celeb split got this ugly -- and we have a feeling it's only going to get worse!

Pamela Anderson filed for divorce from Rick Salomon in February for the third time (they've been married twice now), and now she's filed a restraining order against her ex-husband -- and some dirty details about their marriage have been leaked via court documents.

In the legal docs Anderson included emails that Salomon allegedly sent, in which he claims she had several abortions during their marriage. "I did not [know] she was a serial baby killer to her husbands...she should be locked up," he reportedly wrote in one, adding that Anderson begged him for a baby during their first marriage, but then terminated the pregnancy. Salomon also dragged Anderson's ex-husband Kid Rock into the mess and added, "You never disclosed to me that you (redacted) a baby when you were married to kid rock. I heard you begged him to get pregnant with him too. I also heard it might have also been twice with him."

As far as the real reason why she's getting a restraining order, Anderson claims that Salomon spit in her face, and tried to strangle her and smother her with a pillow when the two had sex in January. She also claims that he has called her an "ugly old b*tch" and "crack wh*re." Yikes! What next?!
