"The Real Housewives of New York" star Ramona Singer is now a single woman.

"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," the reality television star tweeted, according to the NY Daily News.

Singer and her husband Mario have been married for more than 20 years.

Despite her tweet, Ramona Singer didn't take it too well when Andy Cohen asked her about her love life during the show's reunion special.

"So, how's your love life? Who are you going to have sex with tonight? Tell me," the 57-year-old snapped, according to Access Hollywood.

The RHONY star added, "I'm not talking about this anymore. This is a personal matter. I want this closed down. I'm my own person. I'm a great person. I have my life. I have myself and whatever will be, will be."

Housewife LuAnn de Lesseps chimed in the discussion stating, "It's hard when your other half cheats on you, Ramona."

Singer didn't take the comment well, screaming, "Don't even go there! I want this closed down! Stop it, Andy. I don't want to talk about it."

The cheating allegations were reportedly confirmed when Mario was seen stepping out with his reported mistress Kasey Dexter, according to In Touch Weekly.

Singer reportedly threw Mario out in late July after "she discovered he was back with his mistress."
