It was a family affair when Ricky Lauren appeared at the East Hampton Ralph Lauren store to sign copies of her book, “Ricky Lauren: The Hamptons — Food, Family and History.” We’re told that David Lauren and Lauren Bush Lauren had freshly arrived back from the Olympics in London for the event Friday. Also at the signing, with food by Elegant Affairs, were Ralph Lauren, daughter Dylan and guests Alec Baldwin and Hilaria Thomas, Sharon Bush and Russell Simmons. Bush Lauren was also out East for an event Saturday to launch her Feed Foundation’s partnership with Women’s Health on a series of 10K races that will raise money and awareness for world hunger. The New York race will be held Sept. 23.
