Baby Buggy Bedtime Bash

Mingle with celebs (the Seinfelds, Mariska Hargitay, Tiffani Theissen, Bridget Moynahan, Lily Aldrige, Jeff Gorden and Ingrid Vandebosch) and their kids at this charity bash, where they'll be carnival rides, face painting and arts and crafts. Tickets are pricey, but all proceeds benefit the non-profit Baby Buggy, providing products and services to families in need. Tickets must be purchased in advance. Ages 1 to 12.
