Lizzo took a rather silly reference to hair in a recent episode of ‘South Park’ and elevated it into a hilarious Halloween costume.

The Grammy-winning singer shared a series of new posts to her verified Instagram on Saturday showing off her outfit, which consisted of a fake drug box with her name on it, along with some warnings in small print, including “FDA approved,” “Diet suppressant ‘ and “For single patient use only.”

Instead of a belt, Lizzo wore a measuring tape that closed the sheath dress around her waist.

In her first photo, Lizzo posed in an old-fashioned print ad asking, “Do you need self-love?” Try Lizzo! Lose guilt, gain self-confidence.” Her caption for the post read: “Okay Halloween… you can start now.”

Subsequent posts included a video clip of Lizzo dancing in her costume in front of a cutout of “South Park” character Cartman, while audio from the Ozempic episode of the show played.

The May episode, titled “South Park: The End of Obesity,” satirized the increasing popularity of weight-loss drugs such as Ozempic and Mounjaro, and featured a parody ad for a fake product called “Lizzo.”

In a scene from the show, “South Park” characters Sharon and Sheila discuss the “amazing” new medications Sharon has been taking to control her weight, but since her insurance only covers weight-loss medications for people with diabetes, Sharon reveals, ” There is a brand new anti-obesity drug for those of us who can’t afford Ozempic and Mounjaro.”

The scene then cuts to a fake commercial for “Lizzo,” a drug that “makes you feel good about your weight, and it costs 90% less than Ozempic.”

“In case studies, 70% of patients on Lizzo no longer cared how much they weighed,” says the narrator of the fake commercial.

“Lizzo helps you eat all you want and keep physical activity to a minimum… Ask about the power of not giving a fuck, with Lizzo,” the commercial adds, along with a series of side effects.

In her live reaction video on Instagram and TikTok at the time, Lizzo said, “That’s crazy, I just feel like damn, I’m really that b*tch.”

“I really showed the world how to love yourself and not give a f**k, to the point where these guys in Colorado know who I am, and put it in their cartoon that’s been around for 25 years, she added, referring to “South Park” creators Trey Parker and Matt Stone, who met at the University of Colorado Boulder and hosted the show in the state.

Lizzo has long advocated for body positivity and has spoken out on social media about the body shame she faces.
