Ramona Singer files for divorce from husband Mario Singer after years of allegations that Mario was cheating on Ramona. The Real Housewives of New York stars ended their 22 year marriage Tuesday with a painful divorce after getting to know the famous New York couple for years on Bravo.

Allegedly, Ramona files for divorce because Mario had a 27-year-old girlfriend on the side for at least a year. RHONY co-star, Jill Zarin, said, "Ramona has been protecting him [Mario]. She looked the other way when people told her he was cheating." Jill is not alone. We all knew Mario was cheating on Ramona!

Back in 2011, On Real Housewives Of New York, Ramona had a psychic reading that said, "There's another woman." The other Housewives acting taken aback but clearly knew Mario was seeing someone else besides Ramona. The only woman that looked genuinely shocked at the news was Ramona. Sonja and LuAnnne looked horrified for Ramona, who acted entertained as if the psychic was full of c**p. Poor Ramona. 

Ramona, 57, is coping with the divorce by concentrating on her daughter Avery, 19. Ramona tweeted:

"Thank you all for the love & support!" she wrote. "For my daughter's sake, I would appreciate everyone respecting our privacy during this difficult time."

Meanwhile The Real Housewives Of New York returns on March 11.

"Oh, there's a lot of crazy stuff that goes on. We filmed all over- the Berkshires, the Hamptons. We went to some great places." Ramona said about the new season.

"There's a total 180 on the new girls who were all nicey-nicey last year. This year you see their other side. They don't have the patience they had last year. But you always see that with the newcomers, they come on all balanced and then they lose their crap," Sonja Morgan told Wetpaint.

"You can always expect the unexpected with reality TV because we don't know how we're going to react. We go into our scenes like "I'm so mad at so-and-so" or "I'm not talking to her," and then after a couple of cocktails it changes. We all have our egos, we're all very independent. And you just can't keep us from holding our tongues, and that's the problem. And especially for a trip away for a few days, it just adds up to TNT," she continued.

We will be watching for signs of Mario's infidelity on the new season of Real Housewives of New York on March 11!
