Meghan Trainor flaunts dramatic body transformation after weight-loss, breast augmentation

All about that new body.

Meghan Trainor flaunted her dramatic body transformation at a movie premiere in Los Angeles on Wednesday, months after admitting to using a weight-loss drug and undergoing a breast augmentation to transform her physique.

The “All About That Bass” singer, 31, walked the red carpet with her husband, Daryl Sabara, ahead of the “Paper” screening, showing off her svelte frame.

Trainor paired a plunging black camisole with short white shorts. Her tiny waist was cinched by an elegant bow featuring a bedazzled buckle.

The pop star completed her look with black pointed-toe heels, styling her blond hair in a wispy updo as long bangs framed her minimally made-up face.

Meanwhile, Sabara, 33, complemented his wife’s ensemble by sporting an all-black outfit.

In March, Trainor revealed she got breast implants and a lift after “having two kids, living a healthier lifestyle and losing weight.”

Around the same time, her slimmer appearance started making headlines, leaving many fans wondering, “Where did all the bass go?”

The following month, she revealed via Instagram that she used diabetes-turned-weight-loss medication Mounjaro to help shed the pounds. (Sabara did the same because the couple does “everything together.”)

At the time, the Grammy winner acknowledged that she did not “look like [she] did 10 years ago.”

Trainor explained that she had “been on a journey to be the healthiest, strongest version” of herself for her and Sabara’s sons: Riley, 4, and Barry, 2.

During a May performance at iHeartRadio’s KIIS-FM Wango Tango, the songstress controversially changed the lyrics of her body-positive track, “All About That Bass.”

Instead of singing, “Yeah, it’s pretty clear: I ain’t no size 2,” she quipped, “Yeah, it’s pretty clear: I got some new boobs.”
