Teigen paired the daring long-sleeved number with gold and diamond jewels, a black and gold clutch and strappy heels for an overall look that was sleek, sexy and super well put together.
The Sports Illustrated swimsuit model attended the awards show along with her husband, singer John Legend, who performed his new song, "Love Me Now" to a romantic background of photos of people in love.
Teigen introduced Legend's performance with her trademark humor and realness. "This next performer is a brilliant musician and a wonderful father, who makes a pretty damn good breakfast sandwich," she said. "He has been known to write love songs about me. What can I say, I'm very inspiring.
"But his songs are bigger than either of us," she continued. "And on the heels of what’s been a really interesting, f***ed up f***ing election for all of us, we can all use a little love tonight."
Teigen, who gave birth to her first child this year, weighed in recently on how celebrities manage to so quickly bounce back after having babies. See what she had to say about losing baby weight in the video below.
