When Meghan Trainor and her husband Daryl Sabara welcomed their third child - daughter Mikey - via surrogate on Sunday, they left the choice of the newborn's middle name with their most trusted advisors.
The 32-year-old Grammy winner and the 33-year-old Spy Kids alum asked their four-year-old son Riley and two-year-old son Barry, who picked the celestial moniker 'Moon.'
'Riley and Barry have been so excited,' Trainor - who boasts 60.5 million social media followers - wrote in her birth announcement Tuesday.
'They even got to choose her middle name. We are going to enjoy our family time now, love you all.'
The Workin' On It podcasters 'are over the moon in love with this precious girl' and revealed they went the surrogacy route after doctors urged them it was 'the safest way for us to be able to continue growing our family.'
Trainor, who's 'not involved' with Ashley Tisdale's 'toxic mom group', underwent a breast augmentation and lift with plastic surgeon Dr. Payman Danielpour last year on top of losing 60lbs using the GLP-1 agonist drug Mounjaro.
The Massachusetts-born blonde also confessed in a TODAY essay last year that she suffered from postpartum depression following the birth of her second child, but would find a way to eventually welcome four children.
Trainor only has five months to bond with baby before she kicks off her 33-date The Get In Girl Tour on June 12 at the Pine Knob Music Theatre in Clarkston, MI.
But first, audiences can catch the Gifts for Me singer portraying a mystery role in Ryan Murphy and Matthew Hodgson's 11-episode series The Beauty, which premieres this Wednesday on FX and Hulu on Disney+.
The sci-fi body horror about a sexually-transmitted treatment will also feature Evan Peters, Ashton Kutcher, Rebecca Hall, Nicola Peltz Beckham, Bella Hadid, Ben Platt, Amelia Gray Hamlin, Peter Gallagher and Vincent D'Onofrio.
Meanwhile, Sabara portrays Derek Kahn in Jim Cummings' five-episode limited series The Screener, which premieres this Friday at the Sundance Film Festival in Park City, UT.
On February 8, the inseparable pair will celebrate the fifth birthday of their eldest child, Riley.
However, the showbiz couple had originally met at a party in 2014.
Trainor - who gets 29.9 million monthly listeners on Spotify - first found fame in 2014 releasing her debut single All About That Bass, which topped the US Billboard Hot 100 chart and sold 11 million copies worldwide.
