Meghan Trainor and her husband, Daryl Sabara, secretly welcomed baby No. 3 via surrogate.

“Jan. 18th 2026,” the “Made You Look” songstress wrote via Instagram Tuesday, alongside photos with the newborn.

“Our baby girl Mikey Moon Trainor has finally made it to the world thanks to our incredible, superwoman surrogate.”

“We are forever grateful to all the doctors, nurses, teams who made this dream possible,” Trainor, 32, added.

“We had endless conversations with our doctors in this journey, and this was the safest way for us to be able to continue growing our family.”

“We are over the moon in love with this precious girl,” the pop star continued, sharing that her sons, Riley, 4, and Barry, 2, are also “so excited.”

“They even got to choose her middle name,” Trainor said. “We are going to enjoy our family time now, love you all🩷🥹🎀.”

The “No” singer shared an emotional photo of herself cradling her newborn, who wore a fresh hospital beanie.

Another showed Riley and Barry adoringly staring at their sister.

In a third photo, Trainor, who was crying, and Sabara, 33, grinned for an adorable selfie with Mikey Moon.

Several celebrities congratulated the “Mother” singer on her new family edition, including Angela Aguilar, who wrote, “Congratulations!! 🩷🩷🩷.”

“CONGRATULATIONS! Welcome to the world Mikey 🤍💕🌙,” Mayan Lopez, the daughter of George Lopez, chimed in.

Trainor and the “Spy Kids” star tied the knot in December 2018, and the pop star has been open about her dream to have four kids.

“This is my dreams,” she told People in 2022, shortly after welcoming her second child. “I’m halfway there.”

Later that year, the “All About That Bass” singer echoed that it was her goal to “be pregnant” in 2023.

Trainor, meanwhile, recently removed herself from speculation that she was involved in the much-talked-about drama surrounding her mom group after former member Ashley Tisdale slammed them as “toxic.”

The hitmaker took to TikTok earlier this month to share her surprised reaction while reading about the drama online in a video paired with her 2025 track “Still Don’t Care.”

“Me finding out about the apparent mom group drama,” she wrote over the clip.
