On Wednesday, the Yummie shapewear designer addressed their feud – and a report that she’s leaving the series after three years as a Housewife. (Bravo did not return requests for comment.)

Though she was coy about her future on RHONY – telling NBC’s New York Live, “We have so much to talk about on what’s happening on the show right now I mean, who can even think about next season, let’s stick to this season” – she had plenty to say about the Countess.

In Tuesday night’s episode, Thomson, 45, fought with de Lesseps, 50, after waking up to find a naked man brought home during the ladies’ dramatic trip to Turks and Caicos.

“This guy, they didn’t know his last name, barely knew his first name, had just flown to the island that night, I found out, you know, our belongings were there, to me it’s just irresponsible,” Thomson said. “Yes, nothing happened, thank god nothing happened, but we’d all be singing a different tune had something happened, or we were robbed, or pictures were taken of us and put on the internet, so it just wasn’t cool!”

Their argument seemingly inspired de Lesseps’ song “Girl Code (Don’t Be So Uncool).”

“It’s a little hard for me to be objective about it, to be honest, because we’re not girls, we re ladies, number one,” Thomson said of her reaction to the song, adding, “LuAnn made this whole stink about being uncool because she was worried I was going to open the door and catch her with somebody.”

Speaking to PEOPLE Now earlier this week, the entrepreneur suggested her former friend followed a “slithery snake pattern.”

“I don’t even recognize LuAnn this season, to be honest with you,” she explained. “LuAnn is always painting someone else to be the villain because LuAnn takes no responsibility for her own behavior or her own actions.”

Costar Carole Radziwell backed up her BFF on Watch What Happens Live on Tuesday night, pointing out that the man de Lesseps brought home was married.

“It’s not girl code to bang some other girl’s husband,” said Radziwell, 51. “I don’t get that.”
