'This Is Us' Star Mandy Moore, 40, Gives Birth to 3rd Child – Baby's Name Stirs Up Online Buzz

Mandy Moore and her husband, Taylor Goldsmith, have announced the birth of their third child, a baby girl. The couple is thrilled to be parents to three beautiful children.

Mandy Moore and her husband, singer-songwriter, Taylor Goldsmith recently welcomed their third child and the baby's name has ignited mixed reactions online.

The actress, beloved for her role as Rebecca Pearson on the hit drama series, welcomed a precious baby girl who just joined her two big brothers, three-year-old August ("Gus") and two-year-old Oscar ("Ozzie").

Taking to Instagram to share the joyful news, the 40-year-old actress posted a stunning black-and-white snapshot, capturing the emotional moment she cradled her newborn daughter while gazing at her husband with a look that said it all—pure love.

"Lou is here!" she began in a heartfelt caption. "Louise Everett Goldsmith arrived happy, healthy, expeditiously, and right in time for Virgo season." With this sweet announcement, Mandy's "Big Three" at home is now complete—and it seems her older boys are just as smitten with their little sister as mom and dad are.

"She is our absolute dream girl and her big brothers are already as obsessed with her as we are," Moore gushed. "Endlessly grateful for our family of 5 (and our very own Big Three) and soaking in every moment of this special time."

As expected, the comments section was flooded with love and support from fans who were eager to congratulate the happy family. "Congratulations! She is the sweetest, and I love her name! Your Big Three family is perfect," one person wrote, clearly catching the clever "This Is Us" reference.

Another follower echoed the sentiment, saying, "Congratulations! What a beautiful name you guys picked for her! Wish you a fast recovery and the best of health!" Someone else gushed, "This picture is so beautiful, I'm instantly crying. The joy on these faces Congratulations on your sweet girl."

But while most fans shared in Moore's joy, others couldn't help but offer some unsolicited opinions on baby names. One critic bluntly questioned, "Louise!!???"—making it clear they weren't on board with her choice. Another took it up a notch, remarking, "Initials is LEG."

Yet the most biting comment came from someone who seemed to have strong feelings about the Moore-Goldsmith family's naming style, writing, "Worst. Baby. Names. Ever. Gus and Louise??????"

But if there's one thing Mandy Moore has shown us over the years, it's resilience—both on-screen and off. While some may quibble over baby names, the actress and her family are firmly focused on their beautiful new chapter.

The actress' celebrations didn't stop at the hospital! Shortly after Louise's arrival, Moore gave fans a peek into the sweet homecoming festivities via her Instagram stories.

She shared a charming snapshot of her two boys standing proudly at what looks like the entrance of their home, where a heartwarming sign above them read, "Welcome home baby Lou."

Fans first heard the baby news on May 31, when Moore and her husband revealed they were expecting their third child. At the time, the actress melted hearts with a photo of August and Oscar holding hands, dressed in matching white T-shirts.

Big brother August's shirt read “Big,” while little Oscar's shirt playfully announced "Middle." Moore's caption perfectly summed up the moment, “Sometimes life imitates art. The third in our own Big Three coming soon." She went on to confirm that the boys would soon welcome a baby sister.

Becoming a mom was a dream Moore always held close to her heart, even when the odds were against her. In a candid moment, the "A Walk to Remember" star shared how she was once told by doctors that her chances of getting pregnant were slim.

But life had a beautiful surprise in store, and soon enough, she and Goldsmith welcomed their first little bundle of joy, August. "I've always wanted to be a mom," she reflected, describing how she and Goldsmith were overjoyed to learn they were expecting.

Today, Moore's home is filled with the delightful chaos of three young children—Gus, Oscar, and their newest addition, baby Louise. "Motherhood is a beautiful, messy, sleepless gift," she shared in January, adding a hint of humor about having two kiddos under two, calling it a "whew!!!😮‍💨" moment.

And while being a real-life mom can be challenging, Moore revealed that her role on "This Is Us" gave her some unexpected training. "Playing Rebecca on #ThisIsUs actually prepared me for it a bit — like changing a diaper for the first time and running around set with 'triplets.'”

But with her real-life family, she's quickly learned that perfection isn't the goal. "As hard as you try and as good-intentioned as you may be, it is impossible to 'get it right' all of the time," Moore admitted.

She and Goldsmith are just embracing each phase as it comes—whether it's potty training one, chasing another in diapers, or adjusting to life with three kids under one roof. "My husband and I looked at each other the other day and we're like, 'This is a good phase,'" she mused, adding that parenting is "an ebb and flow."

But for Mandy, it's all part of the joy of parenting. After all, as she says, "it just gets better." And with her three little ones—it's clear that Moore is relishing every moment of the unpredictable, wonderful journey of motherhood.
