Mario Singer has nothing to hide now that his marriage to estranged wife Ramona Singer is over. Just a few days after the Real Housewives of New York City star revealed via Twitter that she and her husband had split — this time seemingly for good — Mario was photographed out on the town with alleged girlfriend Kyle "Kasey" Dexter in Sag Harbor, N.Y.

Ramona previously denied rumors of Mario's alleged infidelity, but the scandal nevertheless took a toll on their marriage of more than 20 years. She announced their separation in January, after a report claimed he'd cheated, and filed for divorce later that same month.

Within weeks, though, she and her husband had reconciled. "I know my husband loves me, he knows that I love him, and we will see what happens," she told former RHONY star Bethenny Frankel in March, not long after she and Mario were spotted "joking around and being affectionate" on a bowling date.

It appears the reunion was only temporary, however. "I have decided to move on with my life without Mario," Ramona tweeted on Aug. 7, two days after Bravo aired part two of the RHONY reunion, during which she (tensely) told host Andy Cohen that she and her husband were together. "I tried my best to make my marriage work," she added in her headline-making tweet. "I am excited for the new chapter in my life."

Indeed, the Bravo reality star told Us Weekly that same afternoon that she was "feeing great" in the wake of the breakup. "I am doing what is right for me and my daughter Avery, who is the most important person in the world to me," she said of her only child, 19.

One day later, she shared a picture of herself enjoying a leisurely boat ride with a female pal. "On the Azul," she captioned the photo. "Loving and living life."
