Hampton Social @ RossLeonardo DiCaprio hit the Hamptons. Michelle Rodriguez did, too. And Dancing with the Stars made a stop in Chicago.
That's right: It's time to check up on Planet Gossip's celebrity weekend roundup.
Prince rocked the Hamptons. The Purple One was the featured entertainer at the new, private concerts series Hampton Social @ Ross, in East Hampton.
DiCaprio took along his girlfriend, Bar Refaeli. Christie Brinkley danced with Kelly Ripa and her hunky hubby, Mark Consuelo. And I'm told Jon Bon Jovi arrived via private helicopter.
Edie Falco and Kid Rock enjoyed some Pop Burger miniburgers during Prince's set.
Prince, an insider reports, had a no-photo rule. "Put your cameras away," he told the crowd, the insider says. "I get paid for photo shoots."
Rodriguez was also there. I'm told the former Lost star headed to Eugene Remm and Mark Birnbaum's the Estate in Sag Harbor after the Prince gig for a private dinner to celebrate her 29th birthday. She took a twirl in the deejay booth for about 25 minutes.
In Chicago, Joey Fatone, Cheryl Burke and other members of the Dancing with the Stars tour hit Billy Dec's Underground on Saturday. Fatone performed an impromptu cover of "Living on a Prayer" just before Chicago native R. Kelly grabbed the mike to sing his own four songs.
The night before, reality TV star Kristin Cavallari stopped by Underground with her mom.
Here in Los Angeles, Bravo TV threw a bash on Saturday night at Hollywood hot spot Boulevard 3, where Kyle XY star Matt Dallas did some bumping and grinding with Danity Kane's Aundrea Fimbres to Def Leppard's "Pour Some Sugar on Me."
Willie Nelson, I'm told, performed at the wedding of Al and Tipper Gore's daughter Sarah to businessman Bill Lee at the Beverly Hills Hotel.
In Vegas, rocker Benji Madden partied with his fiancée, actress Sophie Monk, at Light nightclub at the Bellagio.
