What a shocker! Not!

Real Housewives of New York star Luann de Lesseps' marriage to husband of eight months Tom D'Agostino is already on the rocks, as the New York Post reports the reality star was seen slapping her beau at a Manhattan eatery after a heated fight.

"[Their marriage] isn’t exactly a match made in heaven. [D'Agostino] hates the whole reality thing and doesn’t want the attention or the scrutiny," a source dished to the outlet.

"There has been friction from the start, [as] they got married so fast, they didn’t really know each other," the source added.

D'Agostino's wandering eye has been one of the main plot lines on the Bravo hit show, and de Lesseps knew about his cheating before they tied the knot. "He screwed up. What he did was wrong ... he did the wrong thing, and he totally recognizes that. I know in my heart of hearts that he loves me," she told People at the time.

Looks like it's about Tom after all...
