The 32-year-old model, who is pregnant with her second child, flashed her burgeoning baby bump in an elegant silver sequin Yanina couture dress with draping and a matching beaded belt. She accessorized her shining look with a silver Tyler Ellis clutch and single-strap heels, and gorgeous diamond dangling earrings. Her honey locks were in a tousled bob and her makeup was glowing with brown smoky eyeshadow and a nude lip.
Meanwhile, the "All of Me" crooner looked debonair in a double-breasted navy suit jacket with black lapel, black trousers, a crisp white button-up and black bow tie.
Prior to the ceremony, the couple donated $200,000 to the Time’s Up Legal Defense Fund “on behalf of the heroic gymnasts of the USA Gymnastics Team.”
The sizable contribution comes after Teigen’s vocal support of the female gymnasts who have come forward about accusations of sexual misconduct against former USA Gymnastics and Michigan State University doctor Larry Nassar, who was sentenced to 40 to 175 years in prison for sexually abusing girls under the guise of medical treatment.
Meanwhile, ET also chatted with the twosome on the red carpet for the Clive Davis Pre-Grammy Gala on Saturday, where Teigen expressed that she's hoping her second baby gets a little more of dad's style this time around.
"I hope baby two is like John a lot," the model shared. "Baby Luna's more like me...and I realized I can be difficult."
