“Dexter explained that her boyfriend Mario Singer and her had an argument,” the police report read. “Dexter stated Singer pushed her against the wall then singer left.”

Although Kasey claimed she had video of the alleged assault, the officer explained how there was no physical action.

“During the interview, I could smell the aroma of alcohol coming from Dexter’s breath,” the report continued. “Dexter was very uncooperative during the interview. Dexter was reluctant to give me information on Singer and what happened. Dexter then refused to let me in the apartment to check and see if Singer was there.”

The blowout fight comes a week before Kasey’s weekend with Christie Brinkley’s ex-husband Peter Cook.

“Kasey and Mario got back together after he evicted her, but then they broke up again,” a source close to Kasey told Radar. “She went to make Mario jealous. They got into a huge fight and he kicked her out, so she agreed to stay with Peter for the weekend.”

Mario and Kasey split in January. He hit her with an eviction notice on January 26, 2018. The Boca Raton Police Department were called three times before the April incident for domestic disturbances over the eviction.

Mario cheated on his wife of 27 years with Kasey. Ramona filed for divorce from him in January 2014.
