Leonardo DiCaprio, holding up his phone to get reception inside New York City club Butter. The actor – casual in a newsboy cap and Lacoste pullover – spent most of his time smoking, sipping on a drink and chatting with his Basketball Diaries costar Michael Rappaport. Also making the scene: Jamie-Lynn Sigler, who chilled in a banquette with boyfriend (and club owner) Scott Sartiano, Tyson Beckford and Cuba Gooding Jr., who danced with a woman to Beyoncé's "Deja Vu."
Eva Mendes, chatting with Hollywood über producers Brad Grey and Bernie Brillstein at a fete for President Bill Clinton at New York City's Gramercy Park Hotel. The following night at the hotel, Courtney Love and Lucy Liu drank mojitos at a post-concert bash for the Rolling Stones.
Carmen Electra, asking for a peek at the pool at New York City's Sky Studios because she remembered seeing it on Sex and the City. The actress was there for a party hosted by cable channel IN HD Mojo to celebrate their new men's programming block. Electra feasted on sushi from Megu and exchanged hellos with Christian Slater.
John Legend, singing an a cappella version of his song "Save Room" at the record release party for his sophomore album Once Again at New York City club PM. The R&B star partied alongside his brothers John and Vaughn and took pictures and gave hugs to fans. When Jay-Z's "Encore" started playing, an excited Legend hopped on top of the banquette and started chanting "Hova, Hova!" along with the track. The club was so filled to capacity that Petra Nemcova and Russell Simmons patiently waited outside to get in.
