Lizzo has hit back at the fat-shamers online.

The Grammy-winning singer took to her official Instagram page to sound off against critics making jokes about her body.

"Today I saw a fat joke about me - in 2025 - and it was viral," she wrote in the caption of a picture of herself lounging in a yellow-and-black snakeskin bikini.

"It was a dumb joke, and they were just laughing at me because I'm fat... Let me be a reminder to everyone to never let anyone shame you for what you choose to do with your body. Because when you're big, they talk s**t; when you're small, they talk s**t. Your body will never be good enough for them because it's not for them. It's for you."

The About Damn Time singer has battled body-shaming trolls for the entirety of her mainstream pop career.

Earlier this year, on an episode of the Just Trish podcast, Lizzo revealed that she tried Ozempic, but ultimately settled on changing her diet for her personal weight loss journey.

"If I get a BBL, mind ur business. If I lose 100lbs, mind ur business. If I gain every pound back and then some... mind ur f**king business," she concluded her caption.

"Anyways, my fat ass stays living with a paid-off mortgage in y'all b**ches heads."

Lizzo's response to her trolls comes just a few days after she made headlines with a Substack essay she published under the title, Cancel Me (Again): A 'Cancelled' Woman's Take on Why Everyone Should Get Cancelled at Least Once.

"Not everybody liked my most recent essay, and that's exactly why I wrote it," she shared in a follow-up post.

"I deserve to be able to express myself like everyone else. I'm human, I've earned the right to be wrong, to be prickly and unlikable sometimes. It's liberating for a recovering chronic people-pleaser like me. Thank you for your comments and criticisms. I welcome it all."
