• Meghan Trainor was diagnosed with auditory processing disorder in childhood, according to multiple interviews, including a 2023 Newsweek report that revisited her health disclosures.

Is Meghan Trainor’s daughter biologically hers?

Meghan Trainor’s daughter Riley is biologically hers: the egg and carrier came via surrogate, but DNA is from Meghan and her husband (US Magazine).

• It sold over 11 million copies worldwide and became a global phenomenon, spawning a body-positive movement.
• Other hits include “Lips Are Movin”, “Dear Future Husband”, and “No” (Billboard).

What this means: Trainor’s debut single remains her signature, but she has consistently charted with follow-ups, proving she is more than a one-hit wonder.

The pattern: Trainor’s family life is tightly intertwined with her health decisions, from surrogacy to surname traditions.

“I had auditory processing disorder – my brain doesn’t hear the same way everyone else does. I had to learn to lip-read and I went to speech therapy.”

– Meghan Trainor, in a 2023 Newsweek interview

In a 2024 podcast, Trainor explained that she used a surrogate because after her surgery, her uterus had scar tissue, making pregnancy unsafe (US Magazine).

On social media in 2024, Trainor denied using Ozempic, stating she was on Mounjaro for gestational diabetes as part of a lifestyle overhaul, and called the speculation harmful (People).

The trade-off for Trainor: sharing her health details invites both support and scrutiny. For a pop star whose brand is body positivity, the consequence of every public disclosure is a double-edged conversation about medical privacy and celebrity authenticity. For her fans, the implication is clear: believe her words, but recognize that not every answer is a full medical record.
