Katy Perry In String Bikini Shows Results Of Her 'Shock Diet'

Katy Perry has been flaunting her incredible weight loss in swimwear as she reveals the diet behind her slimmed-down figure. The singer, 39, has spent much of this summer and fall sparking Ozempic rumors, but a recent reveal seemed to suggest that Katy's weight loss is down to a diet change. In September, the "Woman's World" hitmaker stripped down to a green and yellow bikini while in Brazil, displaying her low body fat as she flaunted her killer curves. Flashing her abs, Katy highlighted her slender waistline, and now fans know what she did to achieve it.

Scroll for the photo. Enjoying a towel-topped lounger as she relaxed in her five-star hotel, Katy sizzled in a stringy triangle bikini with skimpy bottoms. Rocking a green bathing suit with yellow piping, the pop star flashed her super-toned tummy and legs, lying on her back while folding her arms behind her head.

Keeping a poker face as she wore dark shades, Katy added white flip-flops and necklace jewelry, making sure to flaunt some of her tattoos. Fans may not be convinced that Katy's weight loss is down to a nutritional shift, but at least they've got an explanation for it.

Speaking earlier this week, Katy told her Instagram followers: "I eat a lot of hard-boiled eggs because they are a great source of protein."

Even pulling out an egg as she showed off her time-saving hack, the mom of one added: "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." In the video, Katy wore a loose-fitting nightie, also sending out BTS vibes as she rocked her dark locks in bouffant curlers.

Also shared in September was this selfie as Katy Perry slipped her curves into a semi-sheer, skimpy white tank top and flirty miniskirt. Going sexy in snakeskin knee boots, the singer posed holding her phone, this time drawing the eye to both her braless cleavage and her flat stomach.

Per Life & Style, Katy's weight loss isn't related to weight loss drug Ozempic. A friend, who stayed anonymous, told the outlet: "Her weight loss has nothing to do with any help from Ozempic or weight loss drugs," adding that Perry's new body is down to workouts and a change in diet.

"Orlando's been on a huge push himself the past year to get into the best shape of his life and has really motivated Katy to do the same," they added, mentioning actor fiance Orlando Bloom. The report echoed ones confirming that Orlando is basically Katy Perry's trainer and in-house nutritionist, although some fans may still not be convinced.
