Stavros Niachros and Paris Hilton Get Cozy in Miami

On Saturday night in Miami at the Mokai club Paris Hilton got very cozy with her ex-boyfriend Stavros Niachros, and Benji Madden, who is Paris’ current boyfriend, was no where to be seen. A witness told Star Magazine:

"Paris arrived at the nightclub at 2:30am after partying at the Fountainbleau hotel all night, following the Victoria’s Secret fashion show."

"Paris and Stavros were all over each other. They were at the same table for about an hour and then they left together. It didn’t seem like Benji was on her mind at all!"

On Sunday, Benji, who denied Star’s report that he cheated on Paris not once but twice in recent months, was in New York City with his Good Charlotte bandmate and brother Joel to appear on the last episode of MTV’s Total Request Live.

Is Paris cheating on Benji, or is she "just friends" with Stavros?
