Hilary Duff, taking on and off her scarf and passing around her fedora among friends during a night out at Hyde Lounge in West Hollywood. Skipping around her table to chat with her friends, Duff was super animated, an onlooker reports. At one point, the singer was sitting on their laps, throwing her head back and laughing. Before leaving, Duff picked up the tab – then headed out with her pals. Also there: Kelly Osbourne, conversing quietly with her friends.
Lindsay Lohan, drinking a Red Bull at the Plumm in New York. When Samantha Ronson played her song “Rumors,” the actress ran over to the deejay booth exclaiming, “This is our song!” Later in the night, Lohan asked the club’s owner to move the table next to her so she could make room for pal Charlotte Ronson and other friends. And Lohan has been hanging with the Ronson sisters outside the clubs, too. Days later, the trio visited vintage shop What Comes Around Goes Around, where Lohan sifted through the selection of vintage concert T-shirts.
Nicole Kidman, dining with hubby Keith Urban at Cut at the Beverly Wilshire. Accompanied by four friends, the happy pair took a table along the wall with Kidman sitting directly below a portrait of Brad Pitt. While the other members of the table sipped on glasses of Dom Pérignon, Urban and Kidman smiled and whispered to each other – then split an order of asparagus and poached eggs.
Diddy, squeezing in some time on the elliptical machine at Equinox South Beach while his bodyguards chilled in the café, waiting.
