Things are going to get heated in Turks and Caicos as LuAnn de Lesseps loses her cool on Heather Thomson and Carole Radziwill. The ladies of "The Real Housewives of New York City" left the concrete jungle behind for what was supposed to be a relaxing vacation. Unfortunately it's been anything but and it's only getting worse.

Previews for Season 7 episode 15, shared by E! News, show LuAnn, getting into a heated discussion with Heather and Carole after Heather confronts the Countess about strange men having slept in the ladies' vacation home. LuAnn did her best to play it off like no big deal, saying the guys "probably drank too much and passed out upstairs." Unfortunately that did little to quell Heather's discomfort. She pleaded with her to stop being "all, like, uncool," which only further fanned the flames. 

"What are they on a manhunt? And so what if I had a man in my room?," LuAnn said in a confessional interview. "I'm a grown woman I can decide to do what I want with myself."

Following the trip LuAnn decided to capitalize on Heather's "uncool" moment. The countess recorded a new song -- the follow up to her previous hit, "Money Can't Buy You Class" -- called, "Girl Code: Don't Be So Uncool." The song debuted on June 24 during an episode of "Watch What Happens Live."

This isn't the first time LuAnn's found herself in a tight spot regarding men on vacation. During Season 5 of "RHONY" LuAnn came under fire for cheating on then boyfriend Jacques Azoulay with Tomas, whom she met at a local bar in St. Barths. The 50-year-old denied being unfaithful saying Tomas simply drove her back and took a quick tour of the ladies' vacation home before heading back to his place -- alone. Still, many of her cast mates weren't buying it.

Be sure to tune in to "The Real Housewives of New York City" Tuesday at 9 p.m. EDT for all that and more. Check out a clip of the explosive fight below.
