John Legend and Chrissy Teigen are expecting a daughter!

The supermodel shared the exciting news via Instagram on Wednesday along with the announcement of her first-ever Vogue magazine cover, according to E!.

"So proud and honored to have shot the cover of Vogue Thailand! Special to me for so many reasons... one being I am SO PROUD to be Thai," Teigen captioned the post.

"So excited to have shot a Vogue cover (a dream, of course) annnnd a couple minutes after this shot, John and I learned we were having our little baby girl!" she added.

Teigen announced on Instagram in October that she and the "All of me" singer were expecting their first child. "John and I are so happy to announce that we are pregnant," she wrote at the time.

"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," Teigen added.

Teigen was struggling with infertility and opened up about it on her talk show FABLife earlier this year. "John and I were having trouble. We would have had kids five, six years ago if it had happened. But, my gosh, it's been a process," as HNGN previously reported.
