Lance Bass and Michael Turchin are officially married!

The longtime couple tied the knot in front of family and friends at the Park Plaza Hotel in Los Angeles this weekend, E! Online confirmed. Former 'NSYNC members Joey Fatone, JC Chasez and Chris Kirkpatrick were all in attendance.

It's not clear why Justin Timberlake skipped the nuptials, but there have been rumors that his wife, Jessica Biel, is pregnant with their first child. Sources told E! that Chasez and actress Kristen Chenoweth performed a song together for Bass and Turchin's first dance as a married couple.

Jamie-Lynn Sigler and JoAnna Garcia Swisher officiated the ceremony. The entire wedding festivities were filmed and will air in February on E! for the "Lance Loves Michael: The Lance Bass Wedding" special.

Before getting married, Bass spoke to E! and dished on what his big day was going to be like.

"The whole wedding itself is very classy, you know. We wanted to plan something that could last 100 years. When we show out grandchildren this amazing tape of our wedding, the best wedding video ever, I want them to be able to look at this and be like, 'Wow, that stood the test of time.' So we're using a lot of elements in the wedding that are classy and one of those is definitely our first dance," he said. "The song we chose is a song that lasts forever, something that is very special to us."

The "Bye, Bye, Bye" singer also admitted that the ceremony could "borderline tacky" because he has a strange obsession with medieval.  

"I don't know if it's because my name is Lance, and I was just obsessed with Sir Lancelot and that medieval times and royal everything, but I like to have a royal feel, and that's what it's going to feel like. Something very grandiose," Bass told E!. "My only note to the guests were 'I want you to pretend like you're going to a royal wedding at the met ball.' So it can be over the top, high fashion, and just incredible fashion, and that just kind of set the tone for the wedding right there."

Bass and Turchin first stepped out as a couple in 2011, and the former pop star proposed in September 2013.
