Former N Sync member Chris Kirkpatrick married Karly Skladany.
And his team members all attended the wedding, including Justin Timberlake who brought along his wife Jessica Biel.
Chris Kirkpatrick tweeted: "Best wedding advice from JT, and then partied till 3 am singing with Joey and Karly, #cloudnine."
"Great weekend with old friends and family! Happiest time of my life! #offthemarket."
His friend Lance revealed on his SiriusXM radio show last week that the groom "got us the cheapest tuxes there he could possibly get, which I think is so Chris and very lovely. I mean, that's just who he is."
"I think it's hilarious to know that Justin Timberlake is going to be in a Men's Wearhouse tux, ushering the wedding," he added.
