Lizzo showcased her stunning weight loss transformation on Saturday evening as she mingled with fellow celebrities at the Canelo v Crawford fight event held at Allegiant Stadium in Las Vegas.

The four-time Grammy winner, 37, modeled a glamorous skintight pink gown covered in sparkling rhinestones.

She styled the sleeveless frock with a cream-toned fur shawl and heels.

Lizzo rocked flaming red Old Hollywood curls for the star-studded night, which included the likes of Charlize Theron and Sofia Vergara.

The Juice hitmaker opted for full glam makeup, including a glossy nude lip and a youthful pink flush on her cheeks.

After speaking to reporters, she made her way into the event, which was livestreamed on Netflix.

Lizzo attributes her significant weight loss to dedication and discipline, though she has acknowledged utilizing Ozempic and other GLP-1 medications to aid her progress.

‘I’ve tried everything,’ she admitted on the Just Trish podcast in June. 

It’s just the science, for me, calories in vs. calories out. Ozempic works because you eat less food.’

‘It makes you feel full. So, if you can just do that on your own and get mind-over-matter, it’s the same,’ she explained.

She shifted away from her previous junk food vegan lifestyle, during which she consumed between 3,000 and 5,000 calories daily, toward a more structured eating regimen.

‘For me, adopting whole foods and incorporating beef, chicken, and fish into my diet meant I felt satisfied without stretching my stomach with artificial foods that didn’t truly fill me up.’

Lizzo wasn’t the only big name at Saturday night’s Canelo v Crawford event.

Charlize Theron looked sensational as she stepped in front of red carpet cameras in skinny black leather slacks and pointy booties.

The Oscar-winner, 50, styled her sexy pants with a low-cut bodysuit and a fitted black blazer.

Her blonde bob was styled in soft waves that framed her face as she smiled.

Modern Family star Sofia Vergara was also on hand.

The actress, 53, exuded bombshell glamour in a busty black dress with a lace bodice.

Vergara stood on tall heels and her signature brunette hair fell down her chest in loose curls. 

Charlie Sheen — who recently released a bombshell Netflix documentary — joined in on the fun in Las Vegas.

The actor, 60, posed up on the red carpet in a casual look that featured a black baseball cap and sneakers.

Disney Channel alum Brenda Song — who is engaged to Macaulay Culkin — cut a stylish figure as she paired mini shorts with a black leather jacket.

The actress, 37, was later spotted inside Allegiant Stadium enjoying the fight with her husband-to-be, 45.

The loved-up couple, who have been together since 2017, are parents to two children: Dakota, four, and Carson, three.

Josh Duhamel, Tracy Morgan, Mark Wahlberg and SNL’s Michael Che were also among the high-profile celebrity attendees.
