Paris Hilton & Travis Barker kiss! Plus: Carmen Electra, Jessica Simpson and more star sightings

• Paris Hilton and Travis Barker, making out in full view of clubgoers at New York City hot spot Butter at a party hosted by Kanye West. The duo snuggled and whispered in a corner banquette in the back of the club and the rocker – who is divorcing Shanna Moakler – had his arm around her. When West's song "Diamonds from Sierra Leone" began playing, Hilton stood up and started dancing near Barker. So, what's brewing between the two? "They like each other. Paris really likes him. Beyond that I cannot comment," says Hilton's rep. "Paris is single right now. You may in the future see her in the company of other men."

Also making the scene: Usher, Lil' Kim, Nick Cannon, Serena Williams and Nicky Hilton.

• Jessica Simpson, chilling with Jamie-Lynn Sigler and Scott Sartiano at New York City club Pink Elephant. Another night at the venue, Carmen Electra danced the night away to Madonna's "Hung Up" and Justin Timberlake's "SexyBack" at a Fashion Week bash for design line Imitation of Christ. After hanging out with some male admirers and actress Leelee Sobieski for a while, Electra took off to Bungalow 8.
