had their arms around each other as they took in the festivities at The Surf Club in Montauk, N.Y., during a birthday bash for Allure
magazine's editor-in-chief Linda Wells. The party took place at the venue's outdoor space – and there was plenty of entertainment. Jimmy Buffett
sang "Happy Birthday" and the band Playing for Change performed. Guests also noshed on mini burgers, lobster rolls and birthday cake.
