Meghan Trainor Teases Song About How She Was 'Too Thick'

On November 5, she teased a new song, "Still Don't Care," that claps back at haters of her body transformation. The lyrics include, "Say I'm doing too much / You're probably right / That's the same s--- I've heard my whole life / Said I was too thick, then I got way too thin / And I try to stand out but I want to fit in / You're a little too loud / Stretch marks on your skin / Can't believe you're still here."
Fans took to the comments of her Instagram Reel teaser to further express their surprise over her fresh figure.
"You just don’t look like yourself anymore, sweetheart. I think that’s where people are having an issue," one user wrote.
"You did base your entire identity on all about that base and female empowerment and the second you could get your hands on medication meant for diabetics… you took it. You can see how people might find you a bit disingenuous," another said.

Meghan Trainor Shouts Out Mounjaro for Helping With Weight Loss
Meghan Trainor has been open about using a GLP-1 for help with her body transformation.
In March, Trainor revealed that she used Mounjaro to aid in her weight loss.
"I’ve been on a journey to be the healthiest, strongest version of myself for my kids and for me," she captioned a March 31 Instagram post. "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. And I’m so glad I did because I feel great."
Meghan Trainor hired a fitness coach to help her lose weight.
Sabara worked alongside his wife and also used the GLP-1 medication.
"We heard more and more of our friends — and even our doctors — were on Mounjaro and Ozempic. We decided to give it a go because it had fewer side effects than other weight loss drugs," Trainor said on the April 9 episode of her "Workin' on It" podcast.
