The 'N Sync singer, 35, said "I do" at the lavish Park Plaza Hotel in a 15-minute ceremony. The star-studded guest list included Joey Fatone, Backstreet Boys singer AJ McLean, Emmanuelle Chriqui, Lisa Vanderpump, Cheryl Burke, Carmen Electra, and Kris Jenner, who was accompanied by her boyfriend Corey Gamble.
According to one attendee, revelers seriously got down on the dance floor — even dancing to 'N Sync classic "Bye Bye Bye," with Joey Fatone later singing a song for guets. "Lance and Michael were all smiles all night," the observers says of the bash, where guests noshed on Steve's Ice Cream for dessert.
Leading up to the big day, Bass led a countdown on social media using the hashtag #LanceLovesMichael. "Is this real life?! Can't believe in one more day I get to call this gorgeous man my husband!!!" he captioned a pic on Friday. "ICYMI: "The rings just arrived!!"
On Saturday, he added: "Today I marry the man of my dreams. He makes me smile; he makes my heart melt; he makes me….me."
Us broke news in September 2013 that the Mississippi native and model Turchin were engaged. The couple first met at a birthday party in Palm Springs in 2010 and began dating in December 2011.
"Right away, I knew I wanted to get to know him," Bass recently shared in Brides magazine. "I was very attracted to him and I thought he was sweet, but I just wasn't sure how interested he was in me. It was a situation where I knew right away that I wanted to be friends with him, but I had no idea it would lead to a romantic relationship."
This is the first marriage for both. Bass publicly came out as gay in July 2006.
Bass and Turchin's wedding will be featured in a 90-minute E! special in early 2015.
