Hazel and Phinnaeus, twins of megastar Julia Roberts, ran around in New York City's exclusive Gramercy Park recently while younger brother Henry tagged along with the nanny.

Too bad you won't be visiting the lovely oasis of Gramercy: Keys to the private park are granted only to people who live in buildings surrounding it, and the property is tightly controlled.
