After months of staying mum on the topic of a possible split from her husband of over 20 years, Real Housewives of New York star Ramona Singer has confirmed she’s leaving Mario Singer.

She took to Twitter on Thursday to confirm their split after months of cheating rumors.

“I have decided to move on with my life without Mario. I tried my best to make my marriage work. I am excited for the new chapter in my life,” she wrote.

Ramona actually filed for divorce from Mario back in January and tweeted at the time, “For my daughter's sake, I would appreciate everyone respecting our privacy during this difficult time.”

Ramona and Mario share a 19-year-old daughter, Avery Singer, who’s also featured on the Bravo reality show.

Mario has been seeing Kasey Dexter for months now, even though he did briefly reconcile with his wife before getting photographed with Dexter again earlier this week.

During The Real Housewives of New York's reunion show this week, Ramona refused to answer any questions about her estranged husband. She did say, "Mario and I are together," but obviously things have changed since they filmed it.
