Rachael Kneeland filed for divorce from the Terminator 2: Judgement Day star in July 2009 after three years of marriage.
But their relationship has become more volatile since the split and Furlong was twice ordered to stay away from Kneeland last October (09) after she accused him of beating her up following a heated argument.
Furlong has now been handed his third restraining order from Kneeland, banning him from contacting or approaching his ex and their three-year-old son Ethan after allegedly leaving a series of profanity-laced voicemails on her phone, reports TMZ.com.
Kneeland asked a Los Angeles County Superior Court judge to issue the temporary order on Friday (13Aug10), claiming the troubled actor made threats against her boyfriend in the messages.
In the documents, she accuses Furlong of saying, "If he dares hang out with f**king Ethan, I swear to god I'm gonna f**king rip his f**king heart and f**king feed it to him, you understand me? I will f**king rip him a new one, you can f**king, you see if you like him still when his f**king little pretty face is all deformed."
In another voicemail, Furlong is alleged to have told her, "F**k you Rachael. I'm sick of you... you are such f**king vermin... you are a cesspool of s**t, that's what you are, you're nothing, you're nothing."
Kneeland is expected to play the messages for the court during a hearing on 31 August (10).
