Michael Lohan is getting revenge on his ex-fiancee, Erin Muller, the one way he knows how --by releasing an embarrassing audio tape.
RadarOnline.com has obtained the exclusive audio, a recording Lohan made during a fight with Muller. On the tape you can hear her screaming and cursing at Lohan, who seems to remain pretty calm throughout, possibly because he's taping the whole thing.
At one point, Muller rips into Lohan, screaming, "if you're that pathetic that you need a f***ing tape recorder, because everyone knows the s*** you are."
Other highlights include Muller hollering, "I thought you said you were going to f***ing castrate me!"
Erin Muller filed court documents in Nassau County, NY on Monday, asking the court to drop Lohan's harassment allegations against her.
