Bravo's "Real Housewives of New York" stars made some buzz during the New York Fashion Week on Wednesday, September 5. Some of the ladies filmed scenes for the season 11 of the show at Pier 59, but things get a little bit out of hand.

It's once again that time of the year where top designers around the world go to NYC to display their newest collections. Many celebrities are present at the event, like RHONY stars Sonja Morgan, Tinsley Mortimer, Dorinda Medley, and Ramona Singer. These particular stars, however, had some heated drama on set.

According to Celebrity Insider, a witness claimed the RHONY stars got disruptive while talking to each other causing them to make a huge scene. Things got even worse when Nicky Hilton - also a guest at the show - seen being visibly annoyed.

"It was disruptive," the alleged source said. "They were making such a scene."

The casts of RHONY had also filmed during a fashion show before. The stars were also present at Pamella Roland's show back in 2008; the only difference now is that the stars created a hot mess.

As per the insider, RHONY stars will not probably be invited for next year's show, especially how things got out of hand this year.

Despite the claim, the stars seemed to be having a great time at the show and they all looked fabulous. Singer, Morgan, and Mortimer featured a blue color outfit at the event, while Medley chose an all-black ensemble instead.

Meanwhile, the cast and crew of RHONY are currently working for the season 11 of the show. Just last week, the season 10 wrapped out, though Bravo has not yet made any announcements when will be the new season will premiere.

But based on the previous years, RHONY could be expected to return sometime in April of next year. The filming will be on-going for the next few months.

Morgan, Mortimer, Medley, Singer, and Bethenny Frankel are all expected to come back for the next season. However, Carole Radziwill - who has been on the show for the past years - will not be returning for the season 11. She confirmed her departure on the show a few months ago as she got tired filming the series and she just now wanted to focus on other aspects of her career.
