He says they posted comments about him on a website and it is ruining his business.
Now, they've hired a heavy hitter to defend their case.
"I posted on Liarscheatersrus.com because I wanted to warn other women in order to protect them from what I suffered," said Amanda Ryncarz, the defendant.
Amanda Ryncarz apparently posted something not so flattering about her ex-lover Matthew Couloute.
The post read: "He is very, very manipulating, he's an attorney so he's great at lying and covering it up without batting an eye. Our relationship didn't last long as I figured him out pretty quickly but for others, BE FOREWARNED, HE'S SCUM! RUN FAR AWAY!"
Couloute responded with a lawsuit against the 26-year-old and another ex-lover, former roller derby star Stacey Blitsch, the 35-year-old mother of Couloute's young son.
They in turn hired acclaimed women's rights attorney Gloria Allred to represent them in court.
"I am here because I want people to know the truth and I am asking the court to dismiss the lawsuit filed against me," Blitsch said.
Couloute's lawyer doesn't see that happening.
Attorney Louis Zayas told Eyewitness News the two women "Don't have a right to defame Mr. Couloute or interfere with his ability to make a living."
Couloute's lawsuit claims the internet posting is not only false, but has severely impacted his ability to maintain and secure clients.
