“From Bass to Boobs”: Meghan Trainor’s Lyric Change Sparks Debate Among Fans After Weight Loss Reveal

Meghan Trainor is no stranger to catchy lyrics and bold statements, but her recent performance has reignited an old debate — one that touches on body positivity, celebrity evolution, and the pressures of fame.

At iHeartRadio’s Wango Tango, the 30-year-old pop star took the stage to perform her breakout 2014 hit “All About That Bass,” a body-positive anthem that made waves for its empowering message — and its unapologetic shade at size-zero beauty standards. But this time, fans noticed something different. Instead of singing the original lyric, “It’s pretty clear, I ain’t no size two,” Meghan appeared to swap it out for, “It’s pretty clear, I got some new boobs.”

The lyric change comes on the heels of Meghan’s candid admission that she used Mounjaro, a popular weight loss drug originally developed for diabetes, to help shed pounds after her second pregnancy. In an April Instagram post, she wrote, “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.”

While Meghan’s transparency about her journey has earned praise from some, others aren’t thrilled about how it seems to clash with her earlier body-positive messaging. For many fans who once felt seen by her lyrics, the shift in tone feels personal.

“As someone who was not a size 2 when I first heard this song when I was like 13, for her to change the lyrics just feels hypocritical to me,” one fan commented. “Like I’m glad she feels good in her body… but like… man, I don’t know.”

Another viral TikTok comment, which racked up more than 90,000 likes, stated: “‘Big is beautiful until you’re rich enough to change it.’ — story of the entertainment industry.”

To some, Meghan’s lyric swap is a reflection of how fame and wealth can reshape a celebrity’s image — quite literally. “She changed several of the lyrics because she can’t relate anymore,” one person wrote. “Body positivity isn’t a thing when you can afford to change.”

But others have come to Meghan’s defense, pointing out that 10 years have passed since the song’s release and that personal growth and physical transformation are natural over time.

“All About That Bass was released 10 years ago — god forbid a woman’s body changes in that time!” a fan clapped back online. Another chimed in, “Y’all would BASH her if she kept ‘I ain’t no size 2.’ You really can’t please anyone.”

Aside from the Mounjaro conversation, Meghan also recently partnered with Motiva USA to share her decision to undergo breast augmentation surgery. In a video, she explained, “I’ve always struggled with loving my boobs before I got them done. They were never even and were always sagging my whole life.”

So when she cheekily updated her lyric to “I got some new boobs,” she wasn’t just riffing — she was nodding to her own transformation, both physical and personal.

Still, the moment highlights a deeper cultural tension: can a celebrity known for championing body positivity change their body and still represent the same ideals?

For now, Meghan seems to be owning her choices unapologetically. And whether fans are disappointed, inspired, or simply confused, the conversation proves that 10 years later, “All About That Bass” is still sparking plenty of discussion.
