Spies said a luxe tent was set up on the beach in Southampton, complete with chandeliers and champagne, for 40 guests to celebrate Beth’s Social Life magazine cover shot by the shock jock. But “Beth messed up the time,” a spy heard Howard say when the couple arrived long before the scheduled 7:30 p.m. start. Stern further explained they only had an hour to spare, since the party hoppers were expected later at Jerry and Jessica Seinfeld’s Baby Buggy charity bash in Amagansett. Without missing a beat, Elegant Affairs caterer Andrea Correale served the couple dinner for two amid a sea of empty tables. A spy said they stayed long enough to greet arriving guests, including host Justin Mitchell. Later, the Seinfelds’ guests also included Cameron Diaz, Naomi Watts, Kelly Ripa and Alec Baldwin. The fete, co-hosted by Rag & Bone designers Marcus Wainwright and David Neville, raised $333,250.
