Matthews first announced her pregnancy news in September, shortly after the couple, who began dating in their teens, got engaged.

"Mom & Dad, taking a small detour to the wedding❤️," she wrote in a celebratory social media post alongside two photos with her fiancé, in which she held up a sonogram as Mahomes, 25, hugged her belly.

As her due date approaches, Matthews has been taking her followers along as she sets up the nursery to prepare for her daughter's arrival.

In footage documented on her Instagram Stories on Wednesday, Matthews gave a 360-degree view of the baby's room, highlighting the stuffed animal–filled crib and the new wallpaper.

The nursery also has pink curtains and starry-night wall installations, plus a sign that reads "You are my sun, my moon, and all my stars."

In December, friends and family held a baby shower for Matthews.

"Thanks to my gals for going to TX to shower baby girl & I," the mama-to-be wrote alongside one photo, before going on to explain that she and her loved ones had all "quarantined and been COVID tested."

"Thankful to have amazing close friends & family that will stay safe for the sake of me & my baby girl," she added.

For her big day, Matthews showed off her growing baby bump in a pink dress — which matched perfectly with the shower's festive pink decorations.
