'In love': Meghan Trainor welcomes baby number three via surrogate

Meghan Trainor has welcomed her third child into the world – this time through the aid of a surrogate.

The pop star and husband Daryl Sabara have expanded their party of four to five, managing to keep the pregnancy quiet right up until announcing their bub's birth.

"Our baby girl Mikey Moon Trainor has finally made it to the world thanks to our incredible, superwoman surrogate," Trainor acknowledged in an Instagram post.

Opening up about their decision to opt for surrogacy, the singer said she and her Spy Kids star husband had determined it "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," she added.

Trainor then revealed she'd allowed her other two children to play a small but sweet part in Mikey Moon's naming process.

"Riley and Barry have been so excited, they even got to choose her middle name."

Trainor and Sabara officially tied the knot in 2018, welcoming their two sons – now two and four years old, respectively – soon after.

The All About That Bass powerhouse shared a series of truly sweet snaps of her growing family, including a shot of her boys meeting their new baby sister.

The most recently addition to their family has arrived following previous comments from Trainor about being "ready for three more kids" during a 2021 cover interview for PEOPLE.

"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!"

Following her journey to motherhood, the Dear Future Husband hitmaker went on to foray into the world of writing; authoring a parenting book aptly titled Dear Future Mama.

The autobiography aimed to discuss pregnancy, body image, birth and the new-born stage of parenthood in candid fashion.

But Trainor may need to find a new 'mum group' to join in the wake of her most recent child's birth, with her previous group thrown into disarray following an accusatory essay penned by ex-member Ashley Tisdale for The Cut.

Tisdale, who adopted the surname 'French' following her marriage in 2014, alleged the group had turned "toxic" and exclusionary towards her in its later stages, where previously she'd considered its members "her village."

The group included big names such as Trainor, Mandy Moore and Hillary Duff.
