Chrissy Teigen shares video of daughter Luna's first word

March 21 (UPI) -- Chrissy Teigen captured a video Monday of daughter Luna saying her first word.

The 31-year-old model posted a clip of the 11-month-old saying "cat" during a family trip to Morocco with John Legend.

"Ah!!! So many firsts," she captioned the video for her 11.1 million Instagram followers.

Teigen also shared a photo of another first -- Luna wearing her "First bow!" The cute picture received over 853,000 likes.

Teigen and Legend married in 2013, and welcomed Luna in April. The couple are visiting Morocco with their daughter and friends Jen Atkin and Mike Rosenthal, and shared pictures from their trip over the weekend.

"Vacation vibes," Legend wrote Saturday.

Legend recently told People he's done his "best" to support Teigen amid her battle with postpartum depression. The model went public with her diagnosis in the April issue of Glamour.

"I had everything I needed to be happy. And yet, for much of the last year, I felt unhappy. What basically everyone around me -- but me -- knew up until December was this: I have postpartum depression," she shared.

"I'm speaking up now because I want people to know it can happen to anybody and I don't want people who have it to feel embarrassed or to feel alone," the star explained.
