When Chris Kirkpatrick tied the knot with longtime girlfriend Karly Skladany last Saturday, he was surrounded by the people he loved.
“It was family and friends: people I’ve known forever and people I met last year,” he tells PEOPLE exclusively.
Among the people he’s known forever: the other four members of ‘NSYNC. Clad in black Calvin Klein tuxes, Joey Fatone, Lance Bass, JC Chasez and Justin Timberlake served as ushers, escorting the 300 guests to their seats.
Kirkpatrick, 42, proposed to Skladany, 29, in Italy last year. The couple selected the Loews Portofino Bay Hotel in Orlando for their nuptials. “Our wedding had an Italian motif,” he explains. “It’s a special place to us.”
Skladany, who wore a jewel-encrusted gown by Enzoani, chose a hand-carved wedding band with diamonds set in platinum. Kirkpatrick’s featured black diamonds set in tungsten.
After the outdoor ceremony, the guests retreated to a huge ballroom decorated in white, ivory, merlot and gold. Dinner included teriyaki glazed beef medallions, shrimp scampi with roasted asparagus, and whipped potatoes.
The seven-tier cake, by cake designer Anna Cakes, was decorated in ivory, white and gold. Each tier was decorated differently with gold rhinestones, ivory scroll work, and hand-crafted, edible gold bows. The flavors: sweet lemon, coconut cake and yellow/fudge marble cake with Bavarian cream filling.
