Just how laid-back was 'N Syncer Joey Fatone's wedding to his longtime sweetheart Kelly Baldwin? When it came time to cut the cake—a replica of Baldwin's off-the- rack Ulla-Maija dress—the bride wrapped herself in a protective tablecloth. Then "I shoved the cake in his face!" says the exultant bride. "I enjoyed it. But my makeup artist cried when Joey put the cake in my face. And the hairstylist was like, 'Please don't hit the hair 'cause I'll have to wash it.' "

At the Sept. 9 wedding, held at New York's Oheka Castle in Cold Spring Hills, Long Island, even serious moments had levity. When Baldwin, 27, and Fatone, 27, exchanged self-written vows based on the Helen Keller quote "The best and most beautiful things in the world cannot be seen or even touched. They must be felt within the heart," Fatone amused his 255 guests by blurting out an expletive when he couldn't hold back his tears. "It was a surreal dream," says Baldwin. "We kept going, 'Whose wedding are we at?' "

After dinner the band Smash Mouth played and guests sampled a Ferris wheel, giant slide (Joey's mom, "Phyllis Fatone, went up and down in her ball gown) and bumper cars. Despite recent talk of the band's breakup, all four of Fatone's 'N Sync mates came for the festivities—Justin Timberlake solo, Chris Kirkpatrick clad in jeans. "That must be Chris's formal wear," Baldwin jokes. "We're glad he came fully clothed." Fatone doesn't expect any of the guys to follow his lead any time soon. "They're on the 40-year plan. Some of the guys change their girlfriends like they change their underwear," he says with a laugh. Then again, he adds, "I wouldn't have said I'm the marrying kind three or four years ago. But I am now."
