The "Money Can't Buy You Class" singer, Countess LuAnn de Lesseps, wasn't so classy on her trip to St. Barts - allegedly.

"The Real Housewives of New York City" star appeared to have cheated on her boyfriend Jacques Azoulay with a Johnny Depp pirate look-alike during a "Housewives" getaway, and apparently, her relationship is suffering for it.  

"All of the housewives are sent advanced copies of the upcoming episode that is going to be aired a week beforehand," a source told RadarOnline. "Normally, LuAnn and Jacques watch the upcoming episode together but this past week, for the first time in a very long time, they didn't. The footage of LuAnn flirting up a storm with the Johnny Depp look-alike and the revelation that the countess brought him back to the house that night would seriously be a cause of concern for Jacques."

De Lesseps had a very suspicious talk with her friend Catherine, asking her to tell Tomas, the Johnny Depp look-alike, not to say he was with her the night before. She told the fellow "Housewives" cast members that a group of Italian men came to the house since they knew she had not returned to their Saint Barts home alone. However, cast member Carole Radziwill points out she heard de Lesseps and her guest speaking French.

"Compound that with LuAnn's bizarre phone call in which she tells the hot pirate to deny being at the house at all and LuAnn telling Jacques during a telephone call on the vacation that she had run into some of her old Italian friends and Jacques is very, very upset with LuAnn," the source said. "Jacques just doesn't understand why LuAnn would need to lie about the situation at all, unless she has something to hide. Their relationship is very much on the rocks, despite what LuAnn is publicly saying."

However, de Lesseps explained why she told this "white lie" in her Aug. 28 post on her "Bravo" blog.

"My big mistake was trying to avoid the speculation and assumptions by telling a white lie. The problem with telling a white lie is that once you say it, you have to stick to your story, that's why I made the call when I heard that Tomas was coming for dinner that night," she wrote. "Never tell a fib because it can snowball out of control. LESSON LEARNED."

Though she knows the incident looked bad, she wrote, ""What may have looked like infidelity on last night's episode was in reality a ride home with a friend and a tour of the house after an evening of fun on vacation eight months ago. Do you think I would bring a man back to a houseful of housewives (and cameras) if I were planning on having an affair?" 

She also stated that her relationship with Azoulay is as strong as ever.

"As I write this, Jacques and I are on vacation and we couldn't be more united and happy!"

According to another RadarOnline insider source, "LuAnn begged Bravo execs to not air footage of the Captain Sparrow look-alike leaving the vacation house in the very early morning hours. LuAnn was absolutely beside herself at the prospect of the man leaving the house in the same clothes he was wearing the night before being seen on television, especially by her boyfriend."

It is being said that de Lesseps doesn't want to take any responsibility for her actions.

"LuAnn is blaming the show producers for editing footage to make it look like she cheated on Jacques,"  the source said. "LuAnn is steadfast in her denials to Jacques that she cheated on him. Jacques wants to view next week's episode now, but LuAnn is again stalling."
