Stavros Niarchos and Paris Hilton Reportedly Run It Back... Again

No offense to Benji Madden. But we're excited about the latest Paris Hilton rumor!

According to celebrity gossip tabloid OK!, Madden's supposedly serious girlfriend and her ladies' man of an ex-boyfriend were caught cozying up to one another at Miami hot spot Mokai last night. That's right, folks, there's been a Stavros Niarchos sighting!

"They slipped in secretly together holding hands very, very early in the morning," a witness told the magazine. "They were cuddling and whispering together all night. Stavros was making Paris laugh... She couldn't stop smiling when he was around and they were dancing together very closely."

Our staff is equally giddy over the fact that this anorexia-loving, STD-laden (he's gone home with both Mary-Kate Olsen and Lindsay Lohan, remember) shipping heir is back in the news.

"They looked like they were back to their old ways and you never would have thought she had a boyfriend," another source said. "She was all about Stavros. They left together and went back to their hotel."

Sounds like Niarchos spent another night in Paris. He's familiar with the local cuisine there.
