Meghan Trainor has hit back at critics who have been less than kind about her recent transformation.

The singer, who shot to fame writing body-positive anthems like 'All About That Bass' has recently been showing off a drastic new look.

She credits her new physique to working with a personal trainer, changing her diet, and taking the popular GLP-1 medication, Mounjaro.

The drug - which was initially designed to treat people with Type-2 diabetes, but is now approved for weight loss on the NHS - helps manage blood sugar levels and aids in weight loss by altering appetite and metabolism.

Meghan previously announced on Instagram: “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.”

She also revealed she went under the knife to have a boob job following her weight loss.

Many of her fans were upset when she changed an iconic lyric in 'All About That Bass' during a live performance from "Yeah, it’s pretty clear: I ain’t no size two,” to: "Yeah, it’s pretty clear: I got some new boobs.”

Now, the star has lashed out following criticism about her new look after she lost 60lbs, saying it has caused people to 'attack' her.

Meghan told Entertainment Tonight while promoting her forthcoming album Toy With Me: "I’m literally for the first time ever, after having babies, taking care of my health to the highest level and I've never felt better and I look incredible. I feel great, and that's when people attack me."

"I'm taking care of myself, I have to find a way to not be affected by that," she added.

She told PEOPLE magazine that her social media page changed following her transformation: "My page is usually a friendly, happy, mom-loving place, but it took a dark turn."

"People started commenting about my body, saying I'm too thin, and that they don't recognize me anymore. And I was like, 'Oh, I've just been focusing so hard on my health and my fitness that I've never felt better'."

"So, I was confused and sad and was like, 'Oh, it's almost worse now.' I don't know what happened," she confessed.

She wrote a new song inspired by the hate: "I liked the idea of... 'Let me think about it one more time. Nope, I still don't care.' And I know that when I start singing it, it'll be my therapy, my exposure therapy."

The lyrics include: "Said I was too thick, now I got way too thin," as well as talking about 'stretchmarks on her skin', but repeating that she doesn't care in the chorus.

One fan hit back: "You did base your entire identity on All About That Bass 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."

However, one defended her, saying: "She looks great and is setting a good example for her kids."

Tyla has reached out to Trainor's reps for comment.
