Mario singer's former mistress, Kasey Dexter, may have cheated on him, but when he attempted to have her formally evicted from the home they once shared in Palm Beach, Florida, she reportedly threw a major fit and began making threats against the former "Real Housewives of New York City" star. While Dexter reportedly called the police first, claiming she feared for her life, a just-released 911 call seems to suggest that it wasn't Dexter who was in danger.

On February 9, Radar Online shared details of a call Singer made in which the former reality star begged for police to respond to his home during a fight with Dexter.

The fight happened after Singer caught Dexter having sex with another man on a camera hidden in his home. As "Real Housewives of New York City" fans may remember, Singer cheated on his ex-wife, Ramona Singer, with Dexter years ago after 27 years of marriage. Now, it looks like the joke is on him as he deals with the fallout of his ex-girlfriend's infidelity.

Kasey Dexter refused to leave Mario Singer's home

On January 26, Singer took the first step towards kicking Dexter out of his Palm Beach home when he served her with eviction papers. However, after she refused to leave, he was forced to call the police. Then, a while later, police received a second call from Dexter, who requested that a police officer take her to Singer's home so she could pick up some of her belongings.

On another occasion, it was Mario Singer who said he was afraid to return to his apartment because he suspected his ex-girlfriend may still be there. He also said that because he feared she would accuse him of abuse, he didn't want to enter his home without a police escort present. “She may be screwing some guy in my apartment!” Singer added.

Mario Singer offered Kasey Dexter money to leave his home

Singer called 911 again after a fight with Dexter led him to lock himself in one of the rooms in his home. "She’s banging on the door. She’s threatening me," Singer told police at the time. He also said that Kasey Dexter was "out of control" and refusing to vacate the home.

Meanwhile, Dexter told police that it was her home too and said she would not be moving out, despite Singer's offer to pay her $4,000 to do so. “I don’t know what he’s capable of,” Dexter told the authorities.

Police arrived at Mario Singer's previously shared home with Dexter on three separate occasions as a result of their frequent feuds, and confirmed to Radar Online that none of the three arguments turned physical and that no one was ever arrested.
