Katy Perry got fans talking last December, and chatter was largely about her weight as she showed off her slimmed-down figure in a teeny outfit. Flaunting her weight loss at the Jingle Bell Ball in December 2024, the singer highlighted her slender proportions in a red two-piece, going bold in a tube top and miniskirt as fans quickly reacted. Showcasing her minuscule waist as rumors of her alleged Ozempic use spiked, Katy had fans wondering if she looked better before her weight loss. One user even told the 40-year-old to “stop” using the prescription weight loss drug.

Scroll for the photo. Highlighting her abs as she shouted out 2000s fashion trends, Katy sizzled in a red leather top, going bandeau style as she added pops of purple and black from motif detailing on it. Matching her itty-bitty top with her thigh-skimming miniskirt, the “Roar” hitmaker drew the eye to her whittled-down frame while belting out her beats on stage.

Rocking funky, fuzzy white boots rising to the knee, Katy made eyes pop in her loud look, one she completed with silver drop earrings for some glitter.

Sporting her hair tied back and a heavy face of makeup, Katy shouted out ’90s makeup trends with her silvery-blue eyeshadow and matte frosted lip. The mom of one also wore matte foundation as she held a mic, flaunting some of her many tattoos as she entertained the crowd. Fans quickly reacted on The Daily Mail, with many of the comments centering around Katy’s weight loss. While the star has never admitted to using Ozempic, fans seem convinced she’s been taking it.

“She loves that Ozempic. She was pudgy before it and stayed out of the limelight,” one user said. Over 150 others upvoted the comment.

Also thinking that Katy has lost too much weight, another user replied: “She looked better with a little weight on her and I rarely say that. I wonder if shes on ozempic. If so she should stop taking it. She looks drained.” Elsewhere, users alleged that Katy Perry looked “old,” although these comments, too, linked the singer’s appearance to her alleged Ozempic use.

Ozempic has been sweeping Hollywood over the past few years. While stars including Oprah Winfrey, Elon Musk, and Kelly Osbourne have admitted to Ozempic use, celebrities including Kylie Jenner, Christina Aguilera, and Jessica Simpson remain under scrutiny for alleged use.

Users are also alleging that Katy Perry has been hit by “Ozempic face,” a drawn, gaunt face often associated with Ozempic use. “She used to be so pretty and looked very healthy. Ozempic destroyed that,” a further fan said.

In the above photo, Katy once again displayed her weight loss, this time going sheer in a sleeveless red dress.
