Katy Perry has sparked concern that she’s gotten too thin as fans react to her latest photos. The singer, 41, slipped her curves into a glittery silver minidress to wrap up the weekend, and the Instagram snaps didn’t take long to go viral. Showcasing the weight loss she began making headlines for two years ago, Katy highlighted her tiny waist and toned arms in a braless number, sending out party vibes as she posed backstage in Madrid. The “Roar” singer is still performing at concerts for her Lifetimes tour, but nobody was talking about her music as they reacted to these shots.

Scroll for the photos. Modeling a thigh-skimming, bandeau minidress with a strapless finish, Katy drew the eye from her slim neck and shoulders to her curves, flashing a little cleavage in her party-ready look.

The mom of one, who is now dating former Canadian PM Justin Trudeau, rocked slight cups at the chest while going braless, posing solo and with others, with one photo showing her lying on a table while everyone else ate.

Going shimmery and a little ruched while flaunting her slimmed-down legs, Katy lifted her hands to her head in one slide, with another showing her seated in a glam area. Katy wore strappy black heels to dress up her outfit, adding plenty of matte makeup while sporting her dark locks down. The American Idol alum quickly gathered comments as The Daily Mail reposted the photos.

“Almost 60 years later, we see doubles of Twiggy. If being overweight doesn’t hurt them, being underweight through unnecessary meds might take them there,” one fan said.

“Way too skinny,” a second replied, with a third alleging that Katy Perry’s weight loss is down to injections. “Another Ozempic wreck?” the fan asked. While stars including Rebel Wilson and Oprah Winfrey have admitted to using weight loss medication, Katy has never confirmed use. Katy went viral in August with these Miami Beach photos as she was photographed splashing around ocean waters while in a plunging monochrome bikini.

Katy Perry may not have confirmed having used Ozempic, but she has opened up about her diet. Speaking in 2024, she told her social media fans:

“I eat a lot of hard-boiled eggs because they are a great source of protein,” adding: “I don’t crack them on [the plate], I go like this [cracks on forehead]. Ouch, that one really hurt and it had some juice in it.” Katy has also credited ex-fiance Orlando Bloom with being her in-house personal trainer. The former couple, who was together for nine years, ended their relationship in July of this year. Katy swiftly moved on with Trudeau as she co-parents daughter Daisy with Orlando.
