When it comes to mouth-watering eye candy, Paris Hilton seems to prefer the moneyed wedge of feta cheese that is ex-boyfriend Stavros Niarchos to hollow-cheeked Swedish meatball Alex Vaggo.

Just days after the jailbird starlet was repeatedly snapped stepping out with Vaggo, the former pizza boy-turned-model she discovered at a $27-a-night Los Angeles hostel, the New York Post claims she was using her feminine wiles (and by wiles, we mean clunky dance moves) to catch the eye of her sometime Hellenic honey.

Paris, 26, and Stavros, 22, whose fickle romance hit the skids -- again -- earlier this year, popped up in Miami last week for the annual Art Basel extravaganza, with shutterbugs capturing them with their lips looking thisclose as they snuggled up at a nightclub.

But according to the paper, their time in South Beach was crammed with conflict, starting Wednesday night when the Greek billion-heir arrived at a shindig with a woman identified as Caroline Vreeland, who has previously been seen in the company of boorish oily oil heir -- and friend of Paris -- Brandon Davis.

"Paris beelined for Stavros, but he was chatting up Caroline," recounts a snitch. "He was completely ignoring Paris, and she was furious. She shot them evil looks and finally stormed up to them and started screaming at Caroline."

The next night, Hilton is said to have trailed Niarchos, whom the Post says blew her off at a party in Los Angeles a few days back in order to spend time with her newly single frenemy and his quickly flung fling, Lindsay Lohan, to a trio of nightclubs, where the wonky green eye of jealousy allegedly possessed her once again.

"Paris saw that Stavros was with a girl, and she went crazy," says a source at hot spot Mokai. "She literally stood on Stavros' table and began screaming at him. Then she started dancing and trying to get his attention."

Later, when Niarchos and his date headed over to SET, Hilton reportedly followed while continuing to see red.

"Paris went to great lengths trying to get Stavros' date kicked out, begging club security to get rid of the girl," maintains a spy. "Paris was so furious, she ended up walking up to the girl and just punched her."

And that's not the only incident in which Hilton, who just a few months ago told Larry King of her party lifestyle, "I'm frankly sick of it. You know, I've been going out for a long time now ... It's not going to be the mainstay of my life anymore," may have let her hands do the talking.

"Stavros, look at me. See, I'm dancing. Isn't it hot? Why aren't you watching me? I'm bumping and grinding over here, Stavvie. OK, that's it, I'm climbing on the table."

According to People, the wannabe do-gooder and part-time pole dancer also "scuffled" Friday night with a club-goer at Cameo.

Hilton's rep, however, insists she kept her fists to herself, telling the Post that Paris "at no time physically struck anyone. These accusations are completely false."

The mouthpiece adds to People, "Paris did not slap anyone in Miami."

Besides, there's a possibility Hilton and Niarchos may have even gotten along rather swimmingly during their sojourn.

An eyewitness at Mokai tells Ted Casablanca the duo wasn't shy about shaking their moneymakers in unison.

"They were dancing pretty close to each other, and she had her arms around him," recalls an insider. "He was sweaty and whispering what seemed like sweet nothings in her ear."

What's more, the socially active starlet, who was in town to promote her new perfume, Can Can, reportedly arrived on a private jet with her capricious beau and holed up with him at a swanky hotel.

"They spent all week in Miami, shared a room together," a mole tells Perez Hilton, "and [they] find it funny that nightclubs are starting rumors that there's been any drama."

There's even talk the two may go transatlantic by taking a "romantic getaway" to Europe that will include a Led Zeppelin concert.

As for Vaggo, a spy claims to PageSix.com that he and Hilton "never actually dated" and their quantity time together was just a way to give his modeling career a boost.

Meanwhile, Paris' deep thought-free existence is once again being called out by Tina Fey, who eviscerated her last year as "unbelievably dumb and so proud of how dumb she is" during a sit-down with Howard Stern.

"I regret sinking down to that level of discourse," the "30 Rock" mastermind concedes to Playboy, before making us love her even more by continuing, "But Paris is a terrible role model and a terrible young woman. She needs to be ignored."

Fumes Tina, "I work with people who have 12-, 13-, 14-year-old girls who are fascinated by her. They look up to her, and that's not great. You can buy videotapes in which you can see her [lady parts]."
