At least they aren't spreading diseases elsewhere

Paris Hilton is back together with her ex-boyfriend, Greek shipping heir Stavros Niarchos – at least for now.

"We're together now here. We love each other," Hilton, who, like Niarchos, is in Saint-Tropez, told PEOPLE on Monday at Diddy's Unforgivable 50 party aboard a rented yacht.

While talking to PEOPLE, Hilton paused for a moment to call Niarchos on her PDA. "Stav, where are you, baby?" she said. "Come on over. I love you."
On Saturday night, Hilton was seen partying with Niarchos at the VIP Room nightclub, where she treated him to a pole dance. The following night they kissed at the nearby club Les Caves du Roy.

Hilton, 25, and Stavros, 21, split in May after seven months of dating.
