The 27-year-old model shared an Instagram photo of the white gown on Sunday, along with tweets about the 125-person event.
"I know I love beyonce but I didn't realize how much I loved beyonce until the dj played "love on top" and I cry danced," she wrote.
"Too many kind words flooding in. I was serious when I said it was a difficult thing not to share live with you. Love you guys," she said to her Twitter followers.
According to E! News, Teigen wore three Vera Wang designs on her wedding day. She chose the tulle dress for the ceremony and a bodiced gown for the reception. For after-party dancing, Teigen opted for a mermaid-style dress in daring crimson.
"Every time I went in [to Vera Wang] for a fitting, I couldn't stop getting one," Teigen told E! "It's just too pretty."
Legend, 34, also shared photos of the big day on his personal Tumblr.
"The Beginning..." he tweeted.
