There’s a new golden girl in town!

Chrissy Teigen showed off her growing bump on Wednesday while attending the Sinatra 100: An All-Star GRAMMY Concert at the Encore Theater in Las Vegas in honor of the late Frank Sinatra‘s 100th birthday.

The model and cookbook author looked stunning in a form-fitting gold, long-sleeved minidress that featured intricate beading and accentuated her bump.

Teigen, 30, and husband John Legend, who performed at the event, caught up backstage with Alicia Keys, who also honored Sinatra with a performance. And, once seated, the power couple was photobombed by performers Katharine McPhee and Adam Levine, and Levine’s wife Behati Prinsloo.

Legend recently spoke to PEOPLE about preparing for fatherhood.

“It’s pretty exciting that I’ll have a little child running around that is the product of the love that Chrissy and I have for each other,” he says. “I really hope we’ll be good parents!”

The singer added, “I hope our child will be kind and smart and awesome in every way. Hopefully we’ll do the best job we can.”
