"Real Housewives of New York City" star Kelly Killoren Bensimon was arrested last week for misdemeanor assault.
The 40-year-old reality star's boyfriend Nicholas Stefanov told police that she punched him in the face, New York's Daily News reports.
In a criminal complaint obtained by the Daily News, Stefanov claimed that Bensimon hit him and caused a laceration below his left eye.
The TV star turned herself in on Thursday two days after the alleged incident.
"The allegations are by a jilted lover saying she struck him during the course of an argument," Bensimon's attorney Stephen Turano tells the paper. "We deny the charges, and we are hopeful this will be resolved."
Bensimon is due back in court on March 31, says the Daily News.
