Nicole Richie at Bing Summer of Doing Event NYC Pictures

Nicole Richie attended the Bing Summer of Doing Event at the Jacob H. Schiff Playground in NYC yesterday. She stayed cool in a breezy white tee and black jeans and accessorized with pieces from her House of Harlow 1960 jewelry line. The outdoor event was sponsored by Bing and DoSomething.org, which challenges young people to team up and do good for their communities. Nicole did her part during the appearance, donning rubber gloves and joining a group of teenagers to help restore the park's CITYarts Mosaic Peace Wall.

Nicole is in the Big Apple after a Malibu dinner date with Australian model Jessica Hart last week. Between volunteer work and fun with friends, Nicole is gearing up to launch her very first fragrance, Nicole, in September.
