The reality star then continued by adding, 'People are trying to take her down, but she's unresponsive.'
However, one of the producer's on the SiriusXM quickly chimed in to say, 'Reminder, we are being recorded guys, so don't say anything you don't want.'
The video then zoomed in to show Sai's face, revealing that her jaw had dropped open upon hearing the revelation that the conversation had just been recorded. 'Oh, okay,' she finally stated, ending the 30-second reel.
Social media users jumped to the comment section to share their opinions over the clip, with one penning, 'There goes a new storyline! Everyone say thank you Sai!'
One fan of the series typed, 'Sal's face when the producer said y'all are mic'd,' and uploaded a photo of Meryl Streep with her jaw dropped open with the words, 'NOW a warning?!'

Last month in April, it was revealed that Rebecca would be joining the season 15 cast of The Real Housewives Of New York City, per Deadline.
At the time, a source informed the outlet that the fashion designer has already started filming for the new season in an 'unspecified role.'
The topic of the new season was brought up, and the TV personality explained that season 15 'is filming now'
The woman then asked Sai, 'Has it been good? Stressful? How is Rebecca?' which prompted her to have a brief pause before answering. 'She's nice. She's really, really nice, but [she's] kind of boring, to be honest'

She will be joining other cast members that are returning from the 14th season, including: Sai De Silva, Erin Lichy, Brynn Whitfield, Jenna Lyons, Jessel Taank, and Ubah Hassan.
Most recently, it appeared that both Sai and Rebecca were on good terms. On Mother's Day, Minkoff took to her second Instagram page to share a Mother's Day reel, and De Silva replied in the comments with, 'What a lucky mama.'
Rebecca is known for her work and involvement in the fashion industry and in 2018, launched the Female Founder Collective.
The community is, 'a network of businesses led by women that invests in women’s financial power across the socio-economic spectrum by enabling and empowering female-owned businesses,' per Rebecca's official website.
She created her own fashion brand called, Rebecca Minkoff, in 2005 with her brother Uri Minkoff and launched her first ready-to-wear collection four years later.
The businesswoman is also no stranger to the world of Bravo and reality TV, and notably was a guest judge on the network's show called Project Runway.
Rebecca is also married to commercial director, Gavin Bellour - whom she tied the knot with in 2009 - and the couple share four children.
Upon the news of her casting in RHONY, the fashion designer received backlash after it was also revealed she was a Scientologist. However, she has since been supported by her fellow castmates.

Last month in April, Minkoff - who is a high level Scientologist - was pictured in a sprinter van with some of her new co-stars as they filmed a 'gal's trip' for the show's upcoming season.
A photo of the fun moment was shared to social media by Erin Lichy. Rebecca was sitting in the back of the van with Brynn Whitfield, while Erin was in the front seat sandwiched between Ubah Hassan and Jenna Lyons.
The group seemed to be having an incredible time filming, with Jenna and Erin both giggling and smiling in the image.
Minkoff later shared a short video of herself modelling her outfit for the girl's trip, which received gushing comments from both Erin and Sai De Silva.

It comes as Rebecca has faced some backlash from fans after Dailymail.com uncovered her deep ties to Scientology.
Not only is the fashionista and her entire family longtime members of the church and big money donors, her father was also implicated in the tragic death of Lisa McPherson.
A number of RHONY fans have expressed their disappointment over Minkoff joining the new season, with one writing, 'Please don't cast a Scientologist!'
However, some viewers have expressed their excitement at a potentially juicy storyline involving the controversial church.
