Bethenny Frankel didn’t hold back when asked on “Watch What Happens Live” Wednesday about her “Real Housewives of New York City” co-star Ramona Singer.

Singer previously fired insults at Frankel’s late boyfriend Dennis Shields after he was found dead in his Trump Tower apartment in August 2018 from a suspected overdose.

She said of Shields’ intelligence in a scene supposedly filmed three weeks before Shields’ death, “How smart can Dennis be? I mean, he was on drugs.”

Frankel told host Andy Cohen of the comments, “It was in really poor taste. It was actually fairly despicable — that would be a pretty bad word.

“People come up to me and say that over the course of 10 years she’s done some pretty nasty things, but that was by far the worst.”

Frankel said Singer had reportedly asked Bravo for the scenes to be cut from the show.

Singer, for her part, previously wrote on social media, “I cringed when I saw what I said about Dennis in tonight’s episode. It definitely wasn’t one of my finer moments.

“I respected and liked him very much and I sincerely apologize to his family and Bethenny for my thoughtless comments.”
