The bitter divorce between BETHENNY FRANKEL and JASON HOPPY is getting even uglier as NEW OMG DETAILS emerge.

Hoppy’s latest maneuver is to try and stop her from filming in their uber-posh Manhattan apartment and THAT as opened up as a 2nd front in their campaign of marital attrition.

The reality star was filming scenes for her upcoming talk show Bethenny in the $5 million NYC condo recently when her husband tried to shut production down.

“Jason tried to stop the taping. He freaked out and snapped at everybody” an eyewitness said.

The once-happy couple opened their home for their Bravo series Bethenny Ever After, but now Jason wasn’t cooperating.

“Bethenny had to move the shoot to her bedroom,” the witness said.
