'Real Housewives of New York' star LuAnn de Lesseps getting divorced after 7 months

The couple got married over New Year's weekend in December 2016 in Palm Beach despite numerous claims that D'Agostino, 50, was openly cheating on de Lesseps. The allegations continued throughout their short marriage as the former countess' "Real Housewives" castmates continued to question the legitimacy of the union.

"He used to live this really nice life in the city," a source told Page Six of D'Agostino. "He's a private person and all of a sudden he was living this crazy celebrity life. He loved the nurse from Connecticut, not the reality TV star." (De Lesseps is a former nurse.)

De Lesseps, 52, confirmed the news on her Twitter account a mere two minutes after Page Six broke the story.

"It's with great sadness that Tom & I agreed to divorce," she tweeted. "We care for each other very much, hope you respect our privacy during this sad time!"

News of the split conveniently leaked in the week leading up to the upcoming "Real Housewives of New York" seasonfinale, and just a few weeks after de Lesseps filmed this season's reunion special. In other words, she didn't have to discuss her divorce during the taped program.

Regardless, the signs were there. Page Six reported last month that de Lesseps and D'Agostino got into a physical altercation at a "glitzy" Manhattan restaurant, though de Lesseps responded to the allegations by saying that her reported slap was simply a "love tap."

Britney Spears has long put this behind her, but the world still remembers her infamous 55-hour marriage to childhood friend Jason Alexander. Hey, things happen.
It was definitely a wild night in Vegas, and it ended with Carmen Electra marrying quirky basketball player Dennis Rodman at 7 in the morning. They had it annulled nine days later.
Drew Barrymore and Tom Green made an odd pairing, but they stuck it out for a few months. They wed in summer of 2001 and had split by the winter holidays.
A few years after Rick Salomon made his screen debut (?) alongside Paris Hilton in her infamous sex tape, Pamela Anderson snatched him up. They married in 2007, and Pam filed for divorce 60 days later. (They remarried and re-divorced in 2014.)
What it lacked in duration, it owned in overexposure. The much-hyped nuptials of Kim Kardashian and Kris Humphries took place in 2011 and cost an estimated $10 million. The marriage formally ended 72 days later.
