Meghan Trainor struggled to smile as she hit the Jingle Ball stage in Boston, Mᴀssachusetts after revealing she had a botched Botox job.

On Sunday, the 30-year-old Made You Look hitmaker dressed up in a Sєxy-elf look while vocalizing some of her greatest hits at the star-studded festive concert tour.

She wore a plunging sparkly green dress with fuzzy red lining at the hemline and chest paired with glittering knee-high boots and a matching cardigan.

Just two weeks ago, the blonde bombshell urged women not to get lip filler — admitting that she ‘can’t smile anymore’ while on her Workin’ On It podcast.

She said, ‘I got too much Botox and I need help. I messed up. Listen, I’ve had Botox like a handful of times, just a few times, just on my forehead, you know.

‘And 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.’

The GRAMMY winner said, ‘I cannot smile anymore. Everywhere I go, I cannot smile. My face hurts to smile.’

At one point, her older brother Ryan pointed out the artist’s smile had changed, to which she noted that she ‘can’t unsee’ how much it has altered.

On the same podcast, Meghan revealed that she intends to go under the knife now that she has finished breastfeeding for the time being.

The mom-of-two, who shares Riley, three, as well as 16-month-old Barry with husband Daryl Sabara, has lost weight in recent months and as a result her breasts are now ‘saggy sacks.’

Meghan said: ‘I’m getting a boob job. My mommy boobies were full of milk and now they’re empty and then they’re full of milk and now they’re empty.

‘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.’

While currently on the road for the first time in several years and noted that she has had to wear restrictive bras underneath her ‘amazing outfits’ and ‘can’t wait’ for the surgery.

And on Sunday evening, she strutted her stuff on stage and performed to the best of her ability despite dealing with the facial pain.
