• Cameron Diaz, leaving West Hollywood fitness center The Gym on Nemo. The actress sweated through 30 minutes of cardio and then rehydrated with a chilled bottle of Fiji water.

• Jessica Simpson, hanging out with a group of female pals at Dos Caminos Soho, one of her favorite New York City haunts, while boyfriend John Mayer performed at an event for the Robin Hood Foundation. The singer – who wasn't recognized by many restaurant patrons with her brunette hair – drank Blue Pom margaritas, snacked on chips and guacamole and shrimp and plantain empanadas and was very gracious when the restaurant's staff sent complimentary Mexican hot chocolates to the table.

• Green Day bandmates Billie Joe Armstrong, Mike Dirnt and Tre Cool, partying and sipping cocktails at the Chateau Marmont hotel in Hollywood. "It was like I was backstage at a Green Day concert," a hotel guest tells us. "They were surrounded by an entourage of friends and women and were having such a fantastic time."

• Holly Robinson Peete, gushing about friend Eddie Murphy and his romance with Tracey Edmonds. "They're very loving," she told us at the Women in Film "Minority Report" breakfast in Los Angeles. "I mean you can see it. They're really enjoying the relationship, enjoying each other right now. I'm just really happy to see both of them happy." Also joining Peete at the event: Debbie Allen, Dreamgirls star Anika Noni Rose and Eriq LaSalle.
