Ramona Singer, LuAnn de Lesseps Break Down Over Splits on Real Housewives of New York 100th Special

Cat fights, friendships — and heartbreak. Ramona Singer and LuAnn de Lesseps looked back at their past splits during a Watch What Happens Live special with Andy Cohen on Thursday, Sept. 17. The longtime friends and costars dropped by the Bravo show in honor of The Real Housewives of New York City's 100th episode.

Singer, in particular, shed her fair share of tears on RHONY during her marriage woes with now ex-husband Mario Singer. Ramona split from him after 22 years together (and one child, daughter Avery, 19) amid his cheating scandal last year.

"He had a midlife crisis. That's the only way I can rationalize it," she told Cohen Thursday night. "He turned 60, and something snapped."

Ramona, 58, has tried to get back in the dating game since the breakup. In Season 7 of RHONY, she even annoyed her costars when she flirted too heavily with a bar owner named John — completely ignoring her pals in the process — during a Turks and Caicos getaway. Although she has moved on, the winemaker and jewelry designer still gets emotional thinking about her failed marriage.

"Oh my God, we were like that a few years ago. How the hell did this happen?" she asked Cohen after watching old footage of the exes. "I don't know if I can sit back and watch it, because the man he is today — I don't really know who he is anymore."

The Countess could relate to Singer's devastating blow. Married for 16 years, de Lesseps' marriage abruptly ended when her ex-husband, Count Alexandre de Lesseps, told her via email that he had met someone else. The couple called it quits in 2009.

"I feel very lucky that I have this living photo album [from RHONY]. I have those moments forever," she told Cohen of her ex, with whom she shares two children, Noel and Victoria. "Because, I had a wonderful marriage. A beautiful marriage."
