The All About That Bass singer and her husband, actor Daryl Sabara, shared the happy news that they’ve welcomed a baby girl via surrogacy. Alongside sweet family photos, the couple revealed they are now parents to three children. While many fans rushed to congratulate them, others fixated on one surprising detail: their daughter’s name.
A growing family
On January 21, 2026, Trainor announced that their daughter, Mikey Moon Trainor, was born on January 18. She joins her older brothers, Riley, 4, and Barry, 2, officially making the household a family of five.
In a heartfelt Instagram post, Trainor shared tender images of her sons meeting their baby sister for the first time, as well as quiet moments at home. She also took time to acknowledge the woman who helped bring their daughter into the world.
“Jan 18th 2026. Our baby girl Mikey Moon Trainor has finally arrived thanks to our incredible, superwoman surrogate,” she wrote, adding that she is deeply grateful to the medical teams who supported them throughout the journey.
Why surrogacy
Trainor emphasized that choosing surrogacy was a medical decision, not a cosmetic one. After extensive discussions with her doctors, it was determined to be the safest path for growing their family.
She later reiterated her stance amid online criticism, saying she wants people to understand that surrogacy is simply another meaningful way to become parents.
A name that sparked debate
The couple revealed that their sons helped choose their sister’s middle name — a detail that many fans found especially touching. Still, reactions to “Mikey Moon” were mixed. Some praised it as charming and unique, while others called it unusual or joked that it sounded like a fictional character.
Addressing the backlash
Beyond the name, some critics questioned Trainor’s use of a surrogate, prompting her to speak out. She explained that previous traumatic pregnancy experiences, including postpartum PTSD and severe anxiety, played a major role in the decision.
Despite the online noise, Trainor remains focused on what matters most.
“We’re completely in love with this precious girl,” she shared — and for the singer, that joy clearly outweighs any controversy.
