• Ashlee Simpson and Pete Wentz, smiling as they zip together through Los Angeles International Airport. The musical duo reportedly are Eastward bound: Wentz is expected to deejay a post-July 4th party in the Hamptons. His band, Fall Out Boy, is also scheduled to perform at the Live Earth concert in New York on Saturday.

• What does Matthew Perry do on-set when he's not filming? The former Friend caught some air (literally), jumping on a trampoline in the backyard of a Norwalk, Conn. home during a break from shooting his new flick The Laws of Motion. The gravity-defying break apparently did the funnyman good: "He was laughing and joking around with the crew," an observer tells us.

• Jude Law, getting mobbed on the dancefloor by members of South African performance group Young Zulu Warriors during a party he hosted at Kabaret, a London club. As Law was dancing to "SexyBack," he was swarmed by the group. Says a clubgoer: "All the girls were singing, 'You're bringing sexy back' to him. [And] he was dancing with these amazing Zulu guys." Law was at the club to host an event (with ex-wife Sadie Frost) to benefit God's Golden Acre, a group supporting African youth who lost parents to AIDS.

• Funnywoman Wanda Sykes, bowling up a storm during her visit to Pinz bowling alley in Studio City, Calif. The actress was there with a large group of friends – and seemed to be quite the seasoned bowling pro, scoring high and even bringing her own personal ball. No word if she brought her own bowling shoes.

• Diddy, making a grand entrance – after 2 a.m. – to his party at The Whitehouse in Hampton Bays. Fresh from his performance at the Concert for Diana in London, the music mogul greeted clubgoers from the stage, riling everybody up by imploring, "You want to get f---ed up, enjoy yourselves." Later, he directly addressed female clubgoers, saying: "All the ladies that got their own money, put your hands up!" And the crowd went crazy. There was a sea of cell phones snapping his photo when he first took to his VIP platform. And revelers literally shrieked when he arrived.
