BETHENNY FRANKEL caught in cheating scandal with ‘Jersey Shore’ beefcake The Situation!

Rumors are swirling that the 41-year-old former “Real House­wives of New York City” star hooked up with “Jersey Shore” guido Mike “The Situation” Sorrentino – and the fallout from the cheating scandal is threatening to destroy her already troubled marriage!

What’s more, the whispers are mak­ing waves just as she’s getting set to launch a new talk show.

The embarrassing story began to unfold in October, when a web­site printed a “blind item” that read: “Strangest hookup ever…This contro­versial female married A-list reality star spent a good five minutes making out with this second fiddle reality star who thinks he is way better than he is.”

On April 21, the site revealed that the subjects of the item were Bethen­ny and 29-year-old Sorrentino!

“Bethenny has vehemently denied it, calling the rumor ‘a lot of B.S.,’” a source at the Bravo network said.

But her husband of two years, Jason Hoppy, isn’t so sure.

“He’s been suspicious for some time because of all the problems they’ve had,” the source continued. “Bethenny’s marriage to Jason has already been hanging by a thread, and this could finally sink it.”

Bethenny is also worried how the rumor could affect her new talk show, which will begin a test run on FOX stations in June.

“Getting mixed up with someone like Mike Sorrentino, who has just been through rehab, is the last thing Bethenny needs right now,” added the source. “The timing couldn’t be worse.”
