The mother of one was joined by her husband John Legend at Microsoft Theater in Los Angeles.
Chrissy finished off her outfit with black and gold strappy heels that she tied around her ankles, several chunky gold bangles and multiple rings.

Her musician husband coordinated with his stunning wife; he looked dapper in black trousers with a matching button-up.
John added a patterned grey and black blazer to round out his handsome look.
The Grammy Award winning artist was up for Collaboration Of The Year for the song Like I'm Gonna Lose You with Meghan Trainor.
Chrissy stepped on the AMA stage to introduce her husband - who was slated to perform his hit tune Love Me Now.
The TV personality kicked off her sweet speech about John with: "So this next performer is a brilliant musician and a wonderful father, who makes a pretty d**n good breakfast sandwich."
The brunette jokingly added: "And he has been known to write love songs about me. What can I say? I'm very inspiring."
Chrissy further gushed about John, 37, before slipping in a thought about the presidential election.
She said: "But his songs are bigger than either of us. And on the heels on what's been a really interesting f***ed up, f***ing election for all of us, I think we could all use a little love tonight."
She concluded her introduction with: "Performing his new single, Love Me Now, please welcome the love of my life - John Legend."
Chrissy and John, who welcomed their daughter Luna in April, first met in 2007 while on the set of his Stereo music video.
They tied the knot in September 2013 in Lake Como, Italy.
