5th Annual Charity: Ball
From Kristen Chenoweth to "Entourage" star (and this year's host) Adrien Grenier and more than 1,100 others, celebs and philanthropists turned out in droves to support Charity: Water at last year's gala. Each year attendees participate in the sponsored Waterwalk, during which they walk a fraction of the distance an average person in Africa might walk each day while carrying 40 pounds of water. It's all in the spirit of the nonprofit's goal of bringing clean, safe drinking water to people in developing nations, and funds raised last year served more than a million. This year's goal is to top that! So join in one of the most fun philanthropic events of the year and enjoy drinks, music, and an all-around perfect December evening.
