Meghan Trainor has just welcomed a baby girl via surrogacy and has taken to social media to reveal the newborn's very unique name.
The 'All About That Bass' singer and her Spy Kids star husband, Daryl Sabara, are already parents to sons Riley, four, and two-year-old Barry, but now they've added a daughter to their family-of-five over the weekend (18 January).
Meghan took to Instagram earlier today (21 January) to announce the news and shared a series of snaps of her sons meeting their little sister as well as some adorable selfies of the two overjoyed parents.
She captioned the sweet photo dump: "Jan 18th 2026.

"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."

Meghan continued: "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."
Giving fans an update on how her other two children are faring, she rounded off: "Riley and Barry have been so excited, they even got to choose her middle name.
"We are going to enjoy our family time now, love you all."
Fans were absolutely thrilled by the exciting news, with many rushing to the Instagram comments section to share their congratulations for the mum-of-three.

A few others, however, couldn't help but issue their verdicts on the name choice.
"Why do they always give them names like that?" questioned one X user while a second quipped: "Mikey Moon. Sounding like a Disney character/"
A third chimed in: "Did not expect that name but congrats to them honestly."
Others, however, absolutely loved the outside-the-box moniker with a fourth beaming: "So cute, adorable name!"

"That’s such a cute name," echoed another.
And a final X user gushed: "Congratulations to Meghan Trainor and Daryl Sabara on welcoming their baby girl, Mikey Moon Trainor. What a sweet name!"
Meghan, who tied the knot with Daryl back in 2018, previously opened up about how motherhood has changed her for the better.
"Each kid’s going to bring a new version of me that I think is going to be badass - so I need four, at least!" she told PEOPLE back in 2023.
Congratulations, Meghan and Daryl!
