On May 26, eight weeks after exchanging vows with sitcom writer and producer Chris Henchy, 37, in a secret ceremony off the California coast, Brooke Shields, 36, did it again -- this time before 75 relatives and friends, PEOPLE reports in its new issue. Standing on a carpet of rose petals upon the manicured lawn of a family friend's oceanfront Palm Beach estate, Shields, in a strapless silk faille Vera Wang gown and cocktail-length veil, beamed as Henchy read his handwritten vows. "Mine are a little longer," she announced when it was her turn. Among her many pledges: always to laugh at her husband's jokes, "even if I've heard them before." Among the guests: Kathy Griffin, Garry Shandling and Kevin Nealon, as well as Brooke's mother, Teri Shields, 67, who has long had a troubled relationship with her daughter. They hadn't spoken for 18 months until Brooke called two weeks before the event to invite her. Says Brooke's half-sister, Marina Shields Purcell: "It's been a great family reunion."
