Real Housewives of New York star Luann de Lesseps and Tom D’Agostino announced their divorce after seven months, but what was the real reason behind the split? 

According to the Daily Mail, de Lesseps found out that D’Agostino had cheated on her twice, after being shown a photo of the 50-year old kissing another woman. 

And who showed her the photo? Well, it was none other than D’Agostino’s ex-girlfriend and de Lesseps co-star Ramona Singer.

De Lesseps then began investigating her then husband. After building up enough evidence, she publicly confronted D’Agostino in a restaurant in New York. The confrontation sparked a physical argument. 

It is also reported that D’Agostino met up with an old flame while on a trip to The Hamptons with de Lesseps, leaving her alone.

De Lesseps announced their plans to divorce on social media on Tuesday, after seven months of marriage.

“He cheated on her twice and she found out about it,” a close friend of the star told The Daily Mail. “It’s just a matter of him not being able to be faithful. He has been a bachelor his entire life so it was really hard for him to conform to married life.”
