Chrissy Teigen's baby bump is getting the star treatment.

The Sports Illustrated model and hubby John Legend attended Sinatra 100: An All-Star Grammy Concert at the Wynn in Las Vegas Wednesday, where she glowed in a long-sleeved gold dress that featured elaborate bead work. Her handsome husband looked as dashing as ever in a white tuxedo. Despite this gorgeous couple looking flawless, it was the 30-year-old's bump that stole the show.

While the FABLife co-host posed for photos with the "All of Me" crooner, Alicia Keys joined the group and gave Teigen's belly some love. All three stood for photos together, but Keys' hand resting on Teigen's belly is the real treasure here. The "Girl on Fire" songstress has two children of her own, so she knows a thing or two about pregnancy glow and the excitement of welcoming a child.

Both Legend and Teigen couldn't be more excited to become a family of three. "Chrissy is feeling great!" a source close to the supermodel recently told E! News exclusively, adding, "John is being really supportive during Chrissy's pregnancy. It's so cool for [them] to see her belly grow."

The insider continued, "Chrissy is taking good care of herself and making sure everything is going well with the baby. She has been cooking for the holiday season! John and Chrissy will be with their families for the holidays. It's a really happy time for them."

There are some feelings of nervousness, of course.

"Chrissy can't wait to be a mom. She is a little nervous but she knows that they will be great parents," the source noted. "It's a huge blessing for them both. John will definitely be making a few baby songs."

New music and a baby? 2016 is going to be a great year.
