Was Ramona Singer's reunion behavior the result of too much Pinot Grigio?

Ramona Singer Cops To Boob Job: 'I Just Wanted To Enhance What I Already Had'

According to a report, Singer indulged in her signature wine label as she and her co-stars filmed the three-part Real Housewives of New York City reunion special.

“Ramona drank so much of her own wine, which she brought with her to the taping, that she literally fell asleep,” an eyewitness told the New York Daily News' Confidenti@l on Friday. “The ladies broke for lunch, which was ordered into the venue and Ramona supplied her own wine. By the time they had to return to the set, she was out of it.”

Ramona Singer Claims Her Soon-To-Be Ex-Husband Mario Was Addicted To Mistress Kasey Dexter

During the taping, Singer reportedly left set a number of times, and at one point claimed she needed to meditate. Later, claimed the source, Singer requested filming be pased in order for her to use the bathroom -- twice.

Although Singer was open with her messy divorce from Mario throughout season seven, the source claimed she was hesitant to discussed the matter during the reunion, and was likely "tired" out by Cohen's insistence.

In addition to Singer's alleged drinking, there was also drama between Carole Radziwill and Sonja Morgan, after Morgan brought up Radziwill's reported partying with John F. Kennedy, Jr.

The Real Housewives of New York City three-part season seven reunion concludes on Tuesday at 9 p.m. on Bravo. Check out the video below for a sneak peek at the upcoming episode.
