No amount of concealer could cover up the apparent tension between Carole Radziwill and Jill Zarin at a beauty party this week.

The former “Real Housewives of New York City” stars were spotted at Bluemercury’s 20th-anniversary celebration in Manhattan on Tuesday night, where spies spotted Radziwill and Zarin ignoring each other.

“They walked by each other and didn’t say anything,” a spy told Page Six. “They definitely saw each other but seemed like they were ignoring each other.”

Perhaps it was because Zarin, 55, was too busy packing on the PDA with boyfriend Gary Brody, with whom she became Instagram official in December 2018 after her husband, Bobby Zarin, passed away in January of the same year.

Spies told us he kept putting his arm around her and “grazing her butt” as he told her that an executive wanted to send him Taylor Swift‘s new music. They were also overheard discussing the RH Rooftop Restaurant.

Although the two former “Housewives” never starred on the show at the same time, they share an ex-best friend in Bethenny Frankel. Both were close to Frankel, 48, before each fell out with the “Skinnygirl” CEO.

Zarin did make peace with Frankel in front of Bravo cameras at Bobby’s funeral, while Radziwill’s relationship status with Frankel is still thought to be icy.

We’re also told Zarin circled the entire flagship store testing “every single product.”

Meanwhile, Radziwill, 55, socialized in her black see-through dress that showed off her black bra and underwear.
