Paris Hilton has sparked another controversy while partying aboard a yacht in St. Tropez, France on Sunday, July 25. The hotel heiress was snapped flashing what appeared to be a Nazi salute, holding her finger under her nose, to simulate a mustache, and pointing her hand upward.

However, Paris' rep has dismissed the allegation. The rep told Radar Online, "This is totally false. The photos are misrepresented. Paris did not make a reference to Hitler. Much of her family is Jewish as are the majority of her friends and she is very upset and offended at the allegations."

Paris, who wore a short black strapless cocktail dress covered in crystals and beads, was also spotted donning a bright red military cap. The rep addressed the hat, "She was wearing a captains hat given to her in a club, it was not military."

"And that the photos show her with her arm up, she was dancing with both her arms up, scratched her face with one of her hands," the rep further explained. "That provided the basis for photographers to make these erroneous claims."

Paris Hilton, along with her sister Nicky Hilton and their entourage, has been on the party tour since the end of June with the luxury yacht as their temporary home. The Hilton sisters initially traveled to London before heading down to South Africa for the 2010 World Cup.
