Meghan Trainor critics spark Ozempic claims with singer's dramatic weight loss transformation

The "All About That Bass" singer posed up a storm wearing a sheer white dress and T-shirt for a carousel of snaps recently shared on Instagram.

Her subtle post garnered questions about her slimmed-down appearance, though, with fans wondering if Trainor, 31, was using Ozempic.

Fans took to the comments to both praise and ponder Trainor's new look.

One user asked, "'All about that bass'??? Until Ozempic then you are all about that treble."

"LMFAO body positive until you can get your hands on Ozempic," one fan commented, while another wrote, "all about that bass? all about that ozempic."

Another fan posted lyrics to Trainor's most memorable song, "You know I won't be no stick-figure, silicone Barbie doll."

One user wondered, "ozempic? what happened to being body positive?"

Representatives for Trainor did not immediately respond to Fox News Digital's request for comment.

The "Been Like This" songstress previously lost 60 lbs after giving birth to her first son. 

"I was my heaviest I've ever been, I was like over 200 pounds when I C-sectioned him out. I just wasn't feeling great," Trainor told ET Canada. She "challenged" herself to lose the weight gradually.

Late last year, Trainor admitted she went a little too far with Botox, but still has future plans for plastic surgery. 

"Someone convinced me with my little lips that if you did a lip flip, you put filler right above your upper lip, that you could have a beautiful flip on your upper lip. And I could have one for the first time in my whole 30 years of living. It was not true," she said, explaining she had Botox before "a handful of times" on her forehead.

When sharing what lesson she learned from her experience, Trainor said, "It taught me my smile does light up a room, and when it's not there, it's a dim light. I feel like I'm not happy because I can't smile."
