• Demi Moore and husband Ashton Kutcher, catching the action at the 32nd America's Cup regatta in Valencia, Spain. The twosome have been spotted there all weekend – including at a Prada-sponsored pre-party.

• Kate Winslet, filming a Lancôme commercial at Paris's Pont des Arts, overlooking the Seine. Winslet, in a black dress and black peep-toe shoes, embraced a French male model amid a crowd of extras. "She looked fantastic," an onlooker tells us, adding: "She looks perfect in person."

• Luke Wilson, venturing inside Fred Segal in Santa Monica after lunching with a male friend. The Vacancy star, looking L.A. casual in aviator sunglasses, jeans and a brown blazer, made a few laps around the store. According to an onlooker, "He looked so relaxed [and] seemed to enjoy just browsing around."

• Jessica Simpson, partying with a group of friends in a reserved booth at Hollywood hot spot Parc. It was a veritable couples brigade with her: sister Ashlee, who at one point sat in her new beau Pete Wentz's lap; pal Cacee Cobb, with her boyfriend, Scrubs star Donald Faison; and hair stylist Ken Paves, among other friends. Also making the Parc scene: Lance Bass and fellow 'N Sync-er (and Dancing with the Stars contestant) Joey Fatone, who met over vodka cocktails; and another Dancing couple, Cheryl Burke and Matthew Lawrence, sharing some red wine and an affectionate night.

• Adam Brody, holding court in the VIP area of Hollywood's Cabana Club after the premiere of his film In the Land of Women. Brody chatted with party guests including onetime Heroes star Nora Zehetner and former 'N Sync member JC Chasez. Chasez, wearing a scarf around his neck, later made his way over to Brody – and the two shook hands and laughed away in conversation.
