Meghan Trainor announced Tuesday (Jan. 20) that she and husband Daryl Sabara welcomed a third child over the weekend: baby girl Mikey Moon Trainor.

According to the couple’s Instagram post, Mikey Moon was born on Sunday (Jan. 18) “thanks to our incredible, superwoman surrogate.”

“We are forever grateful to all the doctors, nurses, teams who made this dream possible,” the couple wrote alongside a carousel of seven photos, starting with a teary-eyed Trainor holding her newborn daughter. “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.”

A second photo shows Trainor’s two older boys — 4-year-old Riley and 2-year-old Barry — wearing matching “big brother” T-shirts and holding their baby sister.

“Riley and Barry have been so excited, they even got to choose her middle name,” the caption continues. “We are going to enjoy our family time now, love you all.”

The carousel also includes close-ups of Mikey’s face, a selfie of Trainor and Sabara with baby, and an adorable pic of Barry looking lovingly at his little sis.

Trainor and Sabara married in 2018 after just two years of dating. They welcomed Riley in 2021 and Barry in 2023 before Mikey Moon joined their family.

Most recently, Trainor has been poking some lighthearted fun at the mama drama her name has been linked to after Ashley Tisdale published an essay about leaving a “toxic” group of mom friends after feeling excluded by them. On Jan. 8, the pop star broke her silence on the subject by sharing a TikTok in which she frantically types on a computer keyboard with a confused look on her face. “me finding out about the apparent mom group drama,” she captioned the clip, which she appropriately set to her song “Still Don’t Care” — the lead single from her upcoming seventh album, Toy With Me, set for April 24 release.
