Chrissy Teigen bumped her way through LAX the other day as she and hubby John Legend returned from an exotic vacay in Morocco to celebrate the singer's 37th birthday.

As the supermodel's baby bump grows, the thoughtful wife planned a whirlwind trip to celebrate's John's b'day AND Christmas AND New Year's Eve! It was a three-fer!

Teigen is nailing her maternity look -- sporting a form-fitting black top, olive green shirt and black silk duster jacket with lace-up black heels -- and, of course, a black Hermes Birkin bag on her arm. And what better accessory than her adorable hubby on the other arm!
