The gloves are off in the battle between “Real Housewives” Carole Radziwill and LuAnn de Lesseps.

After LuAnn created a new summer song called “Girl Code (Don’t Be So Uncool),” Carole told Page Six she’s recording a tune, “Ya Dumb Hypocrite.” Ouch!

Lesseps is about to release her “Girl Code” tune — but other “Housewives of New York” are sniping that she’s the one who broke all sorts of codes on their recent trip to Turks and Caicos.

Before the vacation from hell — which sources said will take up the final four episodes of the Bravo series — even began, LuAnn took exception to Carole’s dating 30-year-old Adam Kenworthy, LuAnn’s chef and an ex of her niece.

But sources tell us that during the Turks and Caicos trip, “LuAnn hypocritically slept with the 21-year-old son” of an island staffer, and the two “went skinny-dipping in the ocean.”

The source also alleged, “She also hooked up with another guy named David.”

But a friend of de Lesseps’ insisted: “David was part of a group that LuAnn and Ramona [Singer] brought back to the house for drinks. It’s not true about the [21-year-old] at all.”

LuAnn’s song — with the chorus, “Don’t be so uncool/you broke the girl code/cause all that glitters ain’t gold/I gotta let you go” — was inspired by the Turks and Caicos blowup.

When we contacted Radziwill for comment about any beef with LuAnn, she quipped that she’s recording “Ya Dumb Hypocrite.”
