The 29-year-old model showed off the tiniest baby bump on the skincare line's green carpet, wearing a sleek white dress with spaghetti straps.

Teigen announced the baby news on Monday via Instagram, writing, "John and I are so happy to announce that we are pregnant. As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family."

The model has been candid about the couple's fertility struggles, opening up about the media pressure on her FABLife talk show in September.

"Every single time I sit down for an interview with anybody....I will say, just being two years into being married, the questions just come from all over," Teigen said. "It's kind of crazy because I can't imagine being that nosy to be like, 'So, when are the kids coming?' because who knows what somebody's going through."

The Lip Sync Battle co-host revealed that she and Legend have been trying to conceive over the last few years, and have seen fertility doctors.

"John and I were having trouble. We would have had kids five, six years ago if it had happened," Teigen said. "But my gosh, it's been a process."
