When Meghan Trainor's lips are movin', she's definitely not lyin', lyin', lyin'.
Because when it comes to talking about anything, really—from her joint toilet situation with husband Daryl Sabara to the exact details of her latest health journey—the Grammy winner is all about that face value.
"Honestly, I'm an open book," she told USA Today in 2023 when talking about her literal book, Dear Future Mama, touted as a TMI guide to pregnancy, "and I just say everything."
So the idea that she could be hiding any part of her transformation is nah to the ah to the no, no, no.
Which is the same answer she gave when asked if she cared about any negative comments.
"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," she recently told Entertainment Tonight. "And that's when people attack me."
Still, "I'm taking care of myself," she emphasized. "I have to find a way to not be affected by that."
Trainor first made her TikTok followers look when she participated in the stiletto challenge this past August, balancing atop a set of dumbbells.
After, she found a way to respond to the stunned commenters, like one user who wrote, "I did not recognize her at first. What happened?"
The answer, of course, is when she does her walk, walk, she can guarantee your jaw will drop, drop.
And so the 31-year-old showed off her bangin' new 'do by lipsyncing to Megan Thee Stallion’s "Her." Sample lyric: "I don’t care if these b--ches don’t like me. 'Cause, like, I’m pretty as f--k."
Confident, too.
"I've been on a journey to be the healthiest, strongest version of myself for my kids and for me," the mom to sons Riley, 4, and Barry, 2, wrote on Instagram in March. "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."
Because while her mama told her don't worry about your size, she's enjoying feeling as if every inch of her is perfect from the bottom to the top.
Bet we can make you look at everything she's shared about her glow-up.
Meghan Trainor Details Her Bangin' New Look
Because you know Meghan Trainor is all about those bangs she debuted in an August 2025 TikTok. While the musician's goal was to show off her core strength, balancing atop a set of dumbbells as part of the social media stiletto challenge, it's pretty clear that her followers' eyes were looking higher.
As one fan commented of her sleek high pony and new fringe, "OMG I didn't recognize you."
Why Meghan Trainor and Daryl Sabara Started Taking Mounjaro
Though the singer was more than happy with the boom boom that all the boys chase, she and husband Daryl Sabara embarked on a health journey after welcoming first son Riley in February 2021.
Eager to ensure that every inch of them was perfect from the bottom to the top, "We did 75 Hard," she detailed on an April 2025 episode of their Workin’ On It podcast, name-checking the strict 75-day program, "and, man, did we crush."
But after youngest son Barry joined the party in July 2023, continued Trainor, "We heard more and more of our friends—and even our doctors—were on Mounjaro and Ozempic.”
And after doing some thorough research, the couple decided to give it a shot, opting for Mounjaro because they felt it “had less side effects.”
Starting the journey together, they paired the lowest possible dose with balanced meals and plenty of sweat sessions. "We were like, 'We have to make sure we don't lose muscle, that we worked so hard gaining all those years,'" she added. "And we stay in the gym, we work out, we eat right. And we just noticed that we were less hungry."
These days she knows she looks good in her Versace dress. "I feel amazing," Trainor detailed. "Like this thing is incredible. And I have no shame being on it and talking about it."
Meghan Trainor Shares Why She Got a Boob Job
When Trainor revealed her plans to get breast implants after welcoming two kids, the reaction made her do a double take. "I’m just an open book, so I was like, 'I’m getting my boobs done,' and all the comments were so nice," she told E! News in March 2025, weeks after revealing the results. "All the moms were like, ‘absolutely.'"
Because she wasn't lyin', lyin', lyin' when she shared how much she wanted the boost. "I had two babies, I pumped everything out of me and then I lost a bunch of weight, and my boobs were like ‘we’re not boobs,’ you know," she explained. “I was like, ‘I’m going to get some new ones,’ and that was my dream."
How Meghan Trainor Feels About Her New Breasts
As for whether Trainor regrets going under the knife, that would be a nah to the ah to the no, no, no.
"I got my dream boobs and they are gorgeous,” she told E! in March 2025. "I look so good naked.”
Before, she was always looking at her chest sideways.
"I've always struggled with loving my boobs before I got them done," she admitted on Instagram. "These breast implants are the only ones in the world with smooth silk, a surface designed to minimize inflammation so the tissue around the implant stays soft. Honestly, they look and feel amazing."
Meghan Trainor Reveals She Got Too Much Botox
All about that face: "I got too much Botox and I need help," Trainor revealed on a December 2024 episode of her podcast. Though she'd gotten injections of the wrinkle-reducing neurotoxin to her forehead before, this time she'd paired it with some lip filler.
"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," the singer explained. "And I could have one for the first time in my whole 30 years of living, it was not true."
Instead, she detailed, "I cannot smile. My face hurts to smile, to even try."
