Paris Hilton: Celebrity News

Paris Hilton may have officially broken things off with Stavros Niarchos last year, but the couple have been on-again, off-again for months now. Not anymore. Paris has reportedly kicked Stavros to the curb for good after hitting it off with a new man last weekend.

An insider told Life & Style Weekly, "Paris dumped Stavros. She's been getting tired of him for a while. She feels he's just too insecure and immature…Stavros was devastated. He's really bummed out. He was crazy about Paris. Paris says she really cares about him as a friend, but she doesn't want to be in a relationship right now. She loves him, but she's not in love with him."

Maybe Paris doesn't want a relationship with Stavros anymore, but it looks like she's ready for romance with a new guy, "Desperate Housewives's" Josh Henderson. Henderson first vaulted to stardom on the reality show "Popstars" and was in the spotlight again as Ashlee Simpson's jerky boyfriend on her MTV reality show. Henderson and Hilton met on Friday night at Les Deux where, "They were kissing on the couch like two giddy teenagers. It was really cute," a witness told L&S.

It's no wonder that Paris and Josh spent the next night together as L&S's source said, "The chemistry between them was intense." The new couple went to Area on Saturday and "couldn't take their eyes off of each other", according to a snitch for Star magazine. Stavros was clearly far from Paris's mind as she looked on adoringly at Josh. Says the witness, "Paris looked completely smitten with Josh. She just kept smiling and laughing at everything he said, like she was under his spell."

The heiress and her boytoy got into a friend's Hummer after leaving Area. Star's source said, "Paris and Josh sat in the backseat of the car by themselves for about 15 minutes. It was just the two of them talking and flirting. I guess they wanted to have some alone time before heading to Paris' house where she had a St. Patrick's Day party."

When the party kicked off later that night, Stavros was "nowhere in sight," a pal told Star. The Greek shipping heir would likely have gotten jealous if he had shown up for the soiree. Another source on the scene said, "Paris was with Josh most of the night. She appeared to be having a lot of fun. The two were in the kitchen the entire night eating pizza and talking."
