Gwyneth Paltrow was supported by hubby Chris Martin and kids Moses and Apple as she signed copies of her book “It’s All Good: Delicious, Easy Recipes That Will Make You Look Good and Feel Great” at East Hampton’s Authors Night. A huge line formed under the tent at Gardiner Farm, and she ran out of books. But she found a spare for one disappointed fan, crossing out the already written dedication “To Sarah,” and changing it to “To Susie.” Also there were Eric Fischl, Philippe Petit, Nile Rodgers and the indefatigable Dr. Ruth.
