Meghan Trainor upset some fans when she changed the lyrics to her body positivity anthem, “All About that Bass” to reference her recent breast augmentation surgery.
While performing at 102.7 KIIS-FM’s annual star-studded Wango Tango concert in Huntington Beach, Calif., on May 12, Trainer 31, changed the lyrics to her 2014 hit from “Yeah, it’s pretty clear, I ain’t no size two” to “Yeah, it’s pretty clear, I got some new boobs.”

Trainor recently talked to PEOPLE about her breast augmentation, saying, “I feel so girly and I love it, and it makes me so much more confident and it’s like the best decision I ever made.”
“I smile every time I shower,” she told PEOPLE. The “Mother” singer previously shared that her breasts “got big, they got small, they got big, they got small …I’ve lost some weight and I have sags on, just like saggy sacks as boobs.”
The singer recently disclosed that she’d been taking the GLP-1 injectable Mounjaro to lose weight. It’s the brand name for tirzepatide, a drug used to treat Type 2 diabetes. In 2023, the FDA approved it for weight loss.
“I’ve been on a journey to be the healthiest, strongest version of myself for my kids and for me,” Trainor — who shares sons Riley, 4, and Barry, 22 months, with husband, actor Daryl Sabara — said in an Instagram post.
But Trainor’s new look — she performed in a hot pink, sparkly two-piece — and new lyrics upset some fans, according to comments on KIIS-FM’s TikTok of her performance.
“ ‘Big is beautiful until you’re rich enough to change it.’ — story of the entertainment industry,” read one comment.
“There’s no bass left. Ozempic took it all,” still another wrote, referencing the diabetes drug that has become the catchall term for GLP-1 medication.
“She, in fact, was not all about that bass,” added another, while one commenter wrote, “I feel she just morally shouldn’t perform this song anymore.”
Others took issue with her performance itself, saying she had “no energy” and attributed her subdued performance to the weight-loss medication. “She’s got no energy now, too thin,” wrote one, with another adding, “Go girl give us nothing.”

However, some fans defended Trainor, saying, “All about that bass was released 10 years ago – god forbid a womans body changes in that time! 😅”
“She looks healthy and happy in her own skin,” said another, “and that is ALLLLL that matters. Periodddd.”
