It's over for Luann de Lesseps and Tom D'Agostino.
The Real Housewives of New York City star announced on Twitter Thursday that they are ending their marriage after seven months.
"It's with great sadness that Tom & I agreed to divorce," she tweeted Thursday. "We care for each other very much, hope you respect our privacy during this sad time!"
The news comes two weeks after they made headlines over a public argument at a restaurant, after which Luann told E! News the two are "good" and that "sometimes big love affairs...can be tumultuous." In an interview with Andy Cohen on his Bravo show Watch What Happens Live, she denied a report that she slapped Tom, adding, "We have a very passionate love affair going."
A source told E! News Thursday that Luann plans to now go on vacation to "disconnect and take a little time for herself."
"This was a long time coming but Luann had to come to grips with it herself," the source said. "It's a sad time. She married Tom hoping it would last. Unfortunately, expectations were not met."
"Everyone knew this would be the end result, but no one knew it was going to happen today," the source added.
Another source told E! News Luann and Tom have a prenuptial agreement. They have not commented.
This marked his first marriage and the second for Luann, who was married to French Count Alexandre de Lesseps for 16 years before they divorced in 2009. They share two children.
Another insider told E! News Luann's co-stars did not know about her divorce before she announced it.
"Everyone is surprised by the announcement but not shocked by the news," the source said. "Friends had been encouraging her to get out of the marriage."
