Meghan Trainor is thrilled about her new baby.

The “All About That Bass” singer announced that she and her husband Daryl Sabara welcomed a baby girl via surrogate on January 18.

“Our baby girl Mikey Moon Trainor has finally made it to the world thanks to our incredible, superwoman surrogate,” they shared in a joint Instagram post on January 20. “We are over the moon in love with this precious girl.”

Meghan and the Spy Kids actor—who married in 2018—expressed their gratitude to the medical team that assisted with the arrival of their third child.

“We are forever grateful to all the doctors, nurses, and teams who made this dream possible,” they added. “We had endless conversations with our doctors during this journey, and this was the safest way for us to continue growing our family.”

Their sons Riley, 4, and Barry, 2, are equally excited about their new sister—and even helped choose her name to show it.
