Who's Drinking Tap? Sarah Jessica Parker!

UNICEF Ambassador Sarah Jessica Parker raises a glass at the launch of UNICEF’s Tap Project in celebration of World Water Day.

The event launch was sponsored by DKNY and Esquire magazine and held at NYC’s Hearst Tower on Wednesday night.

Tomorrow on World Water Day (March 22), New York City diners will be asked to pay $1 for each glass of water that normally comes free with their meal.

Other native and adoptive New Yorkers who are supporting the Tap Project include Paul Bettany, Tom Colicchio (Top Chef), Rosario Dawson, Jimmy Fallon, Petra Nemcova, Peter Sarsgaard, and Pharrell Williams.

Sex and the City alum Sarah Jessica, 41, hosted the UNICEF Halloween party back in October.
