Mandy Moore welcomes newborn daughter with “This Is Us” callback: 'Our very own big three'

The actress and her husband, Taylor Goldsmith, are also parents to sons Gus, 3, and Ozzie, 2.

Mandy Moore is recreating the magic of This Is Us in her own home.

The musician and actress, who spent six seasons on the popular NBC tearjerker playing Rebecca Pearson — mother to Kevin, Kate, and Randall — is now the mom to her very own Big Three. On Wednesday, Moore announced that she and husband Taylor Goldsmith have welcomed their third baby, daughter Louise.

"Lou is here," Moore wrote on Instagram. "Louise Everett Goldsmith arrived happy, healthy, expeditiously and right in time for Virgo season. She is our absolute dream girl and her big brothers are already as obsessed with her as we are."

She added, "Endlessly grateful for our family of 5 (and our very own big three) and soaking in every moment of this special time."

Moore and Goldsmith, who tied the knot in 2018, are also parents to 3-year-old son August and 2-year-old son Oscar, whom they call Gus and Ozzie. In an Instagram story post just a few hours after her initial post, Moore shared a photo of her sons standing outside in front of a banner reading, "Welcome home, baby Lou."

This isn't the first reference Moore has made to her role on the era-hopping family drama. In fact, she announced her pregnancy by sharing a photo of her boys wearing "Big" and "Middle" T-shirts

"Sometimes life imitates art," she wrote, winking to the Pearson family of five. "The third in our own Big Three coming soon. Can't wait for these boys to have a baby sister."

In recent months, Moore has also been open up about the ups and downs of her third pregnancy, describing it as the most challenging one yet.

"Is it September yet?" Moore wrote in July alongside a mirror selfie. "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."

This Is Us saw Moore star opposite Milo Ventimiglia as the parents of three. Between 2016 and 2022,  the show received 39 Emmy nominations, ultimately winning four: one for Outstanding Lead Actor in a Drama Series for Sterling K. Brown, and three for Outstanding Guest Actor in a Drama Series (two for Ron Cephas Jones and one for Gerald McRaney).
