Meghan Trainor struggled to smile her botched lip fillers, putting on a brave face as she attended the iHeartRadio Jingle Ball in Fort Worth, Texas this Tuesday.

The 30-year-old songstress recently remarked that she 'cannot smile anymore' after getting 'too much Botox' and having filler applied 'right above' her upper lip.

However she gave the task her best effort during her appearance in Fort Worth this week, treating the cameras to a grin as she strutted across the red carpet.

Soldering past her facial mishap, the All About That Bass hitmaker was dressed to impressed in a seasonal outfit that showed off her sculpted physique.

She put on a sizzling display in a red bra-lette with Santa Clause-style fuzzy white trim, baring her cleavage and her enviably taut midriff.

Flaunting her shapely legs in a sparkly pleated miniskirt, she modeled a sleek crimson jacket with matching feathery accents and a saucy set of scarlet go-go boots.

She topped off the look with a Santa hat, letting her signature blonde hairdo cascade freely over her shoulders and sharpening her features with makeup. 

Musicians galore hit the red carpet that evening, including the country singer Dasha, who rocked a tantalizingly high-cut miniskirt.

Allowing her black jacket to slide down her arms, she paid tribute to the Texas setting of Tuesday night's event by modeling a set of blood-red cowgirl boots. 

Saweetie exuded the air of a saucy Snow Maiden in a flesh-flashing ice-blue party dress speckled with snowy silver brocading and trimmed with white, possibly faux fur.

Jason Derulo exuded showbiz magnetism in a retro chic bomber jacket with graphic patches, while Wonho flashed the flesh in a see-through black tank top.

The concert portion of the evening was a star-studded affair as well, with a glittering guest list that included the hip-hop and country fusion artist Shaboozey. 

Dasha tore off her jacket to strut her stuff across the stage, while Meghan kept on the whole Christmas-themed getup she wore to the red carpet. 

The concert comes after Meghan publicly urged women not to get lip filler – admitting that she 'can't smile anymore' after being convinced by a friend to enhance her pout.

Despite announcing that she will be going under the knife to get a boob job, the 30-year-old pop sensation issued a warning against lip procedures after getting her own 'flipped.'

Speaking on her Workin' On It podcast, she said: 'To all my fellow girlies out there, who are in your 30s out there, hi.

'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.'

Meghan, however, went on to add that this was 'not true.'

She continued: 'And also, I cannot smile anymore.'

Meghan's 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.

'Everywhere I go, I cannot smile,' she quipped. 'My face hurts to smile.'

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.'

The All About That Bass hitmaker is 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.

Speaking on her podcast, Meghan told listeners: 'Everywhere I go, I cannot smile. My face hurts to smile'

She continued: '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.

'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!"'

The To The Moon songstress noted that her breast reduction is something she has wanted her 'whole life' and that the procedure will result in a 'huge confidence' boost for her.

'They're not gonna be big, sorry, they're going to be tiny,' she added. 'I mean, it's going to be huge for my confidence.'
