John Legend [1] was on hand to support his pregnant wife, Chrissy Teigen, at her book signing in LA on Tuesday evening. In addition to giving us another peek at her growing belly [2], Chrissy could barely contain her excitement while signing copies of her new cookbook, Cravings: Recipes For All the Food You Want to Eat [3], at Barnes & Noble. February has been quite the busy month for Chrissy, who recently returned from Miami after celebrating her sexy spread [4] in Sports Illustrated's Swimsuit Issue. Just last week, she and John poured on the PDA [5] at a pre-Grammys party before making a stunning appearance at the event itself [6]. Read on for more photos of Chrissy and John, and then prepare to LOL with their funniest moments [7].
