Too bad “The Real Housewives of NYC” cameras weren’t rolling Monday night at the Regency Hotel when Dorinda Medley allegedly had a meltdown and attacked investment banker Sylvester Miniter IV with her high heel.

Multiple witnesses say Medley had come from a well-lubricated lunch at Le Bilboquet before she started inexplicably screaming at Harry Dubin.

“Harry walked into a s - - tshow,” said one source. “When Sylvester tried to be a peacemaker and told Dorinda she was being inappropriate, Dorinda, who had her shoes in her hand, tried to spike him in the head with a high heel.”

Dorinda’s boyfriend John Mahdessian soon showed and up and took her home. Dorinda apologized profusely the next day, sources said.

Dorinda denies she attacked anyone.

“It was her late husband’s birthday. She’d been at his grave all day, and it was just too much for her,” a spokesperson said. “She took her shoes off because her feet hurt.”
