News of their separation comes after months of rumors regarding Mario's alleged infidelity. The New York Post reported back in October that Mario had cheated on Ramona with a young socialite who later became pregnant. At the time, Ramona denied the claims. However, the paper reported on Monday that the two got into a heated argument at their Hamptons house and that police were called to the scene.

Ramona and Mario, who renewed their vows on-air in 2010, have one daughter together, Avery.

The new season of The Real Housewives of New York City premieres on March 11 at 9/8c on Bravo.
