It's now been just over one month since Chrissy Teigen and John Legend suffered the tragic pregnancy loss of their son, Jack.

The couple has since taken steps in the mourning process, with Teigen penning an essay on the experience, and she and Legend returning to social media and live performances in recent weeks. Now, on Saturday night, Teigen revealed a new tribute to Jack, in the form of a tattoo on her wrist.

On Saturday, Teigen shared with followers a few views of her "date night" with Legend. She started by joking in a video about her "naturally frowny mouth," despite her tendency to "laugh and smile" on the regular.

Teigen then added a captionless photo of her and Legend hand-in-hand, displaying the poignant new tattoo honouring Jack—written delicately in lower-case cursive.

Also seen in the "Jack" tattoo picture is the edge of Teigen's family tattoo, which reads "John - Luna - Miles." According to People, Legend is inked with the same tattoo, but with his wife's name in place of his own. Daughter Luna, 4, is the couple's eldest, while son Miles, 2, was born in 2018.

Sadly, back on Sept. 30, Teigen and Legend shared news of their loss at 20-weeks pregnant with son Jack, who would've been their third child. They chronicled the heartbreaking story on social media, receiving an outpouring of love in the days and weeks that have followed.
