Moore and Goldsmith are also parents to sons August "Gus," 3, and Oscar "Ozzie," 22 months.

In June, Moore and Goldsmith announced on Instagram that they would soon be welcoming a daughter. Alongside a photo of Gus and Ozzie holding hands and wearing T-shirts that read "Big" and "Middle,” respectively, the star wrote, "Sometimes life imitates art.”

"The third in our own Big Three coming soon,” she continued in the caption. “Can’t wait for these boys to have a baby sister. 💓💓💓.”

Moore shared that her pregnancy had some ups and downs, noting that the third time around was the hardest one yet.

In July, the Tangled star shared a mirror selfie on her Instagram Stories as she posed in a skin-tight, black tank top that highlighted her baby bump.

"Is it September yet?" Moore asked as she wrote across the photo. "Feeling very grateful to my body AND this pregnancy has been the hardest by far...simply because chasing 2 toddlers is not for the faint of heart."

Moore and the Dawes singer tied the knot in 2018.

"I feel incredibly understood and supported," Moore told PEOPLE following her engagement to Goldsmith. "I feel incredibly lucky to have somebody who is like, 'I got your back.' I found the right person and I feel like we can handle anything together."
