Meghan Trainor ecstatically debuted her new boob job on Instagram this week, declaring she had undergone both an augmentation and a lift.

The 31-year-old proudly displayed the results of the procedures in a video and bared her soul about the insecurities that drove her to go under the knife.

‘I’ve always struggled with loving my boobs before I got them done, because they were never even, were always sagging my whole life,’ she revealed.

As she spoke about the way her breasts used to be, she played some before footage of her posing in the mirror in a sheer white crop top and no bra.

Her post announcing her new surgery was a collaboration with Motiva, the company behind her implants, which she praised for having a ‘natural look and feel.’

‘My breasts look fuller yet completely natural and they complement my body proportions beautifully,’ she said. ‘They’re finally twin sisters and not distant cousins.’

‘I just love your honesty!’ a fan wrote glowingly. ‘I always say I bet Meghan Trainor would be so cool to hang out with ! I just think you’re so funny!’

Her implant reveal comes a few months after she publicly announced that she was planning to have her breasts surgically enhanced.

Meghan is pictured last November, the month she revealed that she was planning to have the procedure and said she had wanted breast implants her ‘whole life’

She first broke the news this past November, saying that she was willing to undergo the procedure because she was no longer lactating.

‘My mommy boobies were full of milk and now they’re empty and then they’re full of milk and now they’re empty,’ she said on her podcast Workin’ On It. 

‘They got big, they got small, they got big, they got small, I’ve lost some weight and I have, like, saggy sacks as boobs,’ the All About That Bᴀss singer dished. 

‘What’s really difficult is when I’m trying on all these amazing outfits for tour and for shows coming up, I have to wear the most supportive bras,’ she said. 

‘It could ruin the outfit and they squeeze my sides. I’ve always joked and said for years, like: “I can’t wait till I can get a boob job!”‘ 

She spilled that she had wanted breast implants her ‘whole life’ and was now ‘gonna have boobies that don’t look at the floor and it’s gonna be huge.’

Meghan clarified: ‘They’re not gonna be big, sorry, they’re going to be tiny. I mean, it’s going to be huge for my confidence.’
