Just weeks after Luann de Lesseps told ET that she was "working on" her marriage to husband Tom D'Agostino, the Real Housewives of New York City star has announced that they are divorcing after seven months of marriage.
"It's with great sadness that Tom and I agreed to divorce," Luann tweeted on Thursday. "We care for each other very much, hope you respect our privacy during this sad time!"

News of the couple's split comes after Luann went on Watch What Happens With Andy Cohen on July 19, and defended her marriage against a Page Six report that claimed that she had slapped her husband in a restaurant during a public argument. The publication also reported that the two were on the verge of a split. "I did not slap him. We have a very passionate love affair going," she said at the time. "I took his face in a very loving way and people took it as a slap."
Further defending her relationship, Luann said, "We never go to bed angry but when we do, when we wake up, we make up."
The 52-year-old reality star also went to bat for her marriage in a statement to ET that same week. "Tom and I are in love and marriage takes work," she said. "We are working on this together."
The couple's relationship did get off to a rocky start when, months before getting married, Luann's RHONY co-star Bethenny Frankel presented evidence that Tom had kissed another woman. The 50-year-old businessman admitted to the tryst, blaming it on a night of heavy drinking.
In an interview with ET months prior to their wedding, Luann shared why she decided to take Tom back. "We love each other," she said. "I always say if you can't forgive the people you love, then who can you forgive? … I'm not going to let a silly kiss ruin the rest of our lives."
This was Luann's second marriage. She was married to Count Alexandre de Lesseps from 1993 to 2009.
