, 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.
, 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.
, 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.
, squeezing in some time on the elliptical machine at Equinox South Beach while his bodyguards chilled in the café, waiting.
, celebrating his 31st birthday at Los Angeles's Green Door Lounge with his wife, Paula Patton,
and their families, including the singer's father. Entering the club as 50 Cent's "It's Your Birthday" refrain played, the singer was met with a kiss from his wife. The 30-person dinner party featured thick cut steaks and personal chocolate birthday cakes for each guest – and, of course, plenty of champagne. After a fleet of birthday toasts, the singer let his friends do the honors of singing "Happy Birthday" as he sat next to his wife. He followed up, saying, "I would be nothing without the people around me. Now turn up the music!" With that, dinner turned into an all-out party, with guests (including Queen Latifah
and Jennifer Esposito
) jamming to songs by Jay-Z and Mary J. Blige.
