Pop superstar Meghan Trainor, who once proudly sang “All About That Bass”, left fans stunned this week after debuting her dramatic new look at the 2025 Baby2Baby gala.
The 31-year-old mom of two looked radiant in a strapless white gown that hugged her slim frame, showing off just how far she’s come since starting her post-baby health journey.
But not everyone recognized her.
“This is Meghan Trainor? Omg,” one fan wrote.
“She lost her bass,” another joked.
Inside Meghan’s transformation
Meghan has been open about her transformation, revealing that her weight loss came after she welcomed her second child.
“I’ve worked with a dietician, made huge lifestyle changes, started exercising with a trainer, and yes, I used science and support (shoutout to Mounjaro!) to help me after my 2nd pregnancy,” she shared earlier this year.

“I’m so glad I did because I feel great.”
The Grammy winner admitted she used the FDA-approved medication Mounjaro (tirzepatide) — a weight-loss jab that helps regulate appetite — alongside a healthy diet and consistent exercise routine.
