This comes after the 64-year-old was also seen at St. Barts and Mar-a-Lago recently.
Singer allegedly attended the Palm Beach, Fla., bash over the weekend for Dr. Gina Gentry Loudon’s birthday party, and U.S. Representative Matt Gaetz was reportedly also in attendance.
Sources also said that Bravo asked the RHONY cast to stay at home to avoid a third shutdown after production was temporarily suspended in October when a crew member tested positive for COVID-19.
Singer has been posting on Instagram as if she is still in Manhattan, but insiders are reportedly concerned that Singer could put everyone at risk after her getaway if the Bravo show resumes soon.
"It’s very stupid," a production source said. "Likely she’ll have to quarantine for a while when she gets back."
One source saw the reality star at Le Petite Plage on Saturday, January 30, and Singer was also seen out and about over the past week.
"She is telling people on the island that she is keeping it as secret due to her contract with Bravo, yet she is taking pictures with people on the island and flew in on a public plane," the source explained.
However, insiders explained that the trip will not be a problem as long as Singer follows CDC guidelines, which means quarantining for seven days when she gets home. Filming may resume during the second week of February.
Singer previously revealed that she and her daughter, Avery, tested positive for COVID-19 antibodies. "We both found out we have the antibodies, so we donated our plasma," she shared, explaining that she felt ill in February 2020 but didn't get tested because she thought her symptoms were from Lyme disease.
"I had no energy," she recalled. "I just wanted to stay in bed all day. I felt very tired, and I also had severe headaches."
Costar Leah McSweeney previously bashed Singer for traveling during the pandemic, but Singer said that she took all the necessary precautions.
Costar LuAnn de Lesseps was also spotted not wearing a mask at a party last week but explained that she “took the mask off for some photos. Knowing everyone had tested negative, I felt comfortable doing that.”
Page Six was the first to report on Singer attending the Palm Beach party.
