Sarah Jessica Parker, helping launch UNICEF's Tap Project for World Water Day, an initiative inviting Big Apple diners to donate $1 for clean drinking water around the world, at an event cohosted by Esquire magazine at New York City's Hearst Tower. The actress, who's a UNICEF ambassador, told us that she's instilling her passion for volunteerism in her 4-year-old son, James Wilkie. "We weren't allowed out of the house with a pillowcase for trick-or-treating if we didn't have a box for UNICEF," Parker told us about growing up. "And my son has been doing the same thing now for two years and he loves it. It gives him a real sense of pride to be a part of something."

Sean "Diddy" Combs, stopping traffic on Paris's Champs-Elysees during a photo shoot. As the hip-hop magnate posed in front of his burgundy Maybach car, a crowd swarmed around him.

Room club to party with tourmate Snoop Dogg and their crews.
