It looks as though Ramona Singer isn't letting negative press about her personal life get her down.

The Real Housewives of New York star recently shared a racy photo of herself in a skin-tight dress before leaving to a charity event in the Hamptons this weekend.

Why Did Ramona Singer Send Kasey Dexter A Threatening Letter?   

The 57-year-old reality television star proved that she is still fit and fabulous, despite rumors that have suggested that her husband Mario Singer has been cheating on her with his mistress, 28-year-old Kasey Dexter.

Singer recently went on a week-long vacation to St. Barth's with her husband where she was supposedly trying to save her 20-year marriage.

Even with their best intentions, it seems as though the trip didn't turn out the way they hoped, with both of them fighting over Ramona's alleged alcohol use.

Ramona Singer's Husband Still Cheating On Her With His Mistress?   

"Ramona and Mario were at the pool on Sunday afternoon, and he was very upset that she had over indulged at dinner Saturday night," a source told Radar Online Monday. "Specifically, according to Mario, Ramona had too much to drink."

The source stated that Ramona must have gotten her husband's message, because by the next day, she swapped her glass of wine for non-alcoholic beverages instead.

"Ramona didn't say much in response to Mario, but did ask him to keep his voice down. She was only drinking water at the pool on Sunday," the source added.

The Real Housewives of New York airs every Sunday at 10 p.m. EST/PST on Bravo.
