luann de lesseps' estranged husband, Tom D'Agostino, is speaking out about the recent end of his marriage to the "Real Housewives of New York City." Just hours before De Lesseps' one-on-one "Watch What Happens Live" special with Andy Cohen is set to air, D'Agostino spoke to E! News about their breakup and revealed a very shocking new detail about the end of their seven-month marriage.

After De Lesseps confirmed her plans for divorce with a tweet to her fans and followers early last month, the reality star made several statements about the end of her relationship and thanked fans for their support.

Meanwhile, D'Agostino chose to stay silent until today.

"I fell in love, got married quickly and am very sad that two people in love are not together," D'Agostino told the outlet. He then seemingly took aim at LuAnn De Lesseps for publicizing false reasons behind their breakup to sensationalize her storyline on "The Real Housewives of New York City."

Why did LuAnn De Lesseps pull the plug on her marriage after just seven months?

During a sneak peek at tonight's "Watch What Happens Live" special with her friend and boss, Andy Cohen, De Lesseps told Cohen that there were allegedly numerous events that led her to call it quits on her marriage. As she explained to Cohen in the preview clip, she reportedly discovered that her husband had made contact with one of his former girlfriends and ultimately met up with the woman and some other friends.

"I found out about it the next day in the press," De Lesseps said of the incident, adding that Tom D'Agostino's outing with his ex-girlfriend was the final straw.

What has LuAnn De Lesseps been doing since her split?

As E! News revealed, the reality star has been doing tons of traveling since she and her husband parted ways last month.

In fact, in addition to taking trips to Mexico and Switzerland, she's been spending tons of time in New York City and The Hamptons. As for who she's been spending time with, De Lesseps has been seen with her "Real Housewives of New York City" co-stars Carole Radziwill and Sonja Morgan, as well as "Sex and the City" author Candace Bushnell and her children, son Noel and daughter Victoria De Lesseps.
