Just two months after the Bye Bye Bye hitmakers - Timberlake, JC Chasez, Joey Fatone and Lance Bass - reunited on stage at the MTV Video Music Awards in August (13), the guys came together once again in Orlando, Florida to celebrate Kirkpatrick's big day.
After recruiting his other close friends as his groomsmen, Kirkpatrick wanted to include his 'N Sync pals in the ceremony by using them as ushers.
Kirkpatrick tells People magazine, "They sat the families, escorted people to their seats. Obviously, they knew what this meant to me, and it was really special that we could all be back together. It was like no time had passed. I wanted them to share the day with us."
Timberlake and Fatone had an extra special role in the proceedings - the two married singers calmed the groom with a series of last-minute pep talks.
Kirkpatrick says, "We were getting ready together in the bathroom, and we laughed that the bathroom was bigger than some of our dressing rooms. We joked and laughed a lot; it really was like how things used to be. They're like family.
"Justin and Joey were giving me wedding advice. Justin was like, 'You're going to be a little bit nervous here, but it'll be okay.' It was really funny. I'm the oldest one of us, and I never thought I'd be getting wedding advice from Justin Timberlake!"
Kirkpatrick has been dating Skladany for more than three years and he popped the question to the marketing rep during a birthday trip to Italy in October last year (12).
