Real Housewives of New York City star Ramona Singer has filed for divorce from Mario Singer following reports she caught him cheating.

Court records show the reality star filed the paperwork Tuesday in Manhattan Supreme Court.

The news comes just days after it was revealed she reportedly walked in on her husband of 22 years at their Hamptons home with 27-year-old Kasey Dexter, who is said to be his girlfriend of a year.

Ramona is undoubtedly going through a hard time, but if she needs some advice, she has these six co-housewives — who’ve each had their own relationship woes — to lean on:

Real Housewives of Beverly Hills: Brandi Glanville

Brandi’s ex-husband, Eddie Cibrian, with whom she has two children, cheated on her with his now wife, LeAnn Rimes, after they met on set of Lifetime’s Northern Lights in 2009.

She left the actor, and they ended up filing for divorce, which was finalized on Sept. 30, 2010.

“I like being single and that there’s not a guy I’m pining for and sad over,” she recently told Life & Style.

“I have a great time with my friends. There’s no one breaking my heart right now. I’m not in that place — I’m happily moving forward.”

Real Housewives of New Jersey: Teresa Giudice

Long before the pair had legal woes, rumors swirled that Teresa’s husband, Joe, had been having multiple affairs behind her back — for years.

She claims none of it is true.

Regardless, the duo have many other things to worry about – like a 41-count fraud indictment.

If convicted, they could each serve more than 50 years in prison.

Real Housewives of Atlanta: Phaedra Parks

Phaedra’s man, Apollo, apparently crossed the line with co-housewife Kenya Moore.

She accused Kenya of propositioning her husband on the show’s reunion last year.

While she insists she never sexted him, Kenya told Life & Style in December, “I do feel I was wrong in responding to his text messages. He’s a married man.”

Ouch.

Real Housewives of Miami: Adriana De Moura

She married Frederic Marq last May, which was shown on the last season, but it appears Adriana had already been a happily married woman for five years!

Her ex-best friend Lea Black accused the brunette of hiding the 2008 marriage so she could tie the knot on television.

Naturally, it stressed Adriana out, and she explained that was not the case.

“In the lust of the first few weeks of dating Frederic, he proposed,” she told Life & Style. “The sex was great, so I said, ‘Yes, I’ll marry you.’”

They signed a marriage license, but called off the wedding because her young son Alex allegedly begged her not to do it.

(Note: We’re pretty sure that still means you're married, A.)

“The legal document never solidified our relationship,” she said. “But after walking down the aisle, I’m living my fairy-tale life with both Frederic and Alex!”

Real Housewives of Orange County: Vicki Gunvalson

Vicki split with her insurance agent husband, Donn, in 2010 after 16 years of marriage. Their divorce was finalized this week.

She blames the show for causing the breakdown of her marriage.

“I think that my family would still be together,” said the mother-of-two, who’s since moved on with Brooks.

“There’s some really great things that have come from the show, but one of the downsides was that it broke up my family, and that’s tough to take.”

Real Housewives of Orange County: Tamra Judge

Tamra’s now ex Simon Barney filed for divorce after 10 years together claiming she was “verbally abusive and committed acts of disloyalty and infidelity.”

The blonde beauty went through a very tough time before finding love again with Eddie Judge, whom she married last June.
