Stavros Niarchos gets around

Greek shipping heir Stavros Niarchos graduated from USC on Friday, but he has been celebrating like a graduate for some time now. He was recently seen "making out" with model Petra Nemcova in New York and, on Saturday, he reunited at Teddy's in Los Angeles with ex Paris Hilton.

A witness for Page Six spotted Niarchos at Bungalow 8 with fellow heir-head, Brandon Davis. It wasn't long before Stavros had found someone more attractive to spend time with. He got frisky with Petra Nemcova on the dancefloor. Said the snitch, "She was grinding him. It was pretty gross. I mean, he used to sleep with Paris. Eww."

On Saturday, Stavros wasted no time flirting with his many admirers and went for the sure thing. He showed up at Teddy's about 45 minutes after Paris arrived and he headed straight for her table. The former couple exchanged a friendly hug and kiss - a preview of what was to come.

Us Weekly claims, "The two spent most of the night together, laughing and cuddling and Paris leaned over and kissed [Stavros] multiple times. We watched as she massaged his neck and ran her fingers through his hair." The pair left Teddy's together about an hour later.
