The SECRET behind Katy Perry's incredible new look revealed - as singer sparks furious Ozempic speculation after showing off toned abs and underboob in shoot for new song Woman's World

Katy Perry had her own ‘break the internet’ moment when she stripped down to a tiny white bikini to promote her big musical comeback.

The singer, 39, shared a sexy photo of herself from a shoot with British photographer Jack Bridgland on Monday as she launched her ‘new era’ with the announcement of her ‘empowering’ upcoming single, Woman's World.

Now insiders have revealed the secret behind her jaw dropping new look – fiancé Orlando Bloom.

The Roar hitmaker has adopted the 47-year-old's diet and exercise routines in preparation for her first album release in four years, cutting out processed foods and curbing her alcohol intake.

‘She loves savory food, she loves chicken nuggets and sugary food, but recently she has been way more disciplined and has chosen to follow Orlando's diet,’ an insider told DailyMail.com.

After unveiling the cover art for Woman's World and sharing a video from the shoot, fans were quick to speculate that she had used a weight loss wonder drug (pictured in 2019)

But Perry's fiancé Orlando Bloom, 47, has been her 'right hand man' when it comes to fitness, with insiders claiming she adopted his diet and exercise routines 

‘She has been working out more because she wants to do some shows to support her upcoming album, so now is the time to look great.

‘Orlando has been her right-hand man and has helped her out. They eat the same and work out the same. She has cut out tons of processed food and doesn't drink that much.

‘She has been looking incredible because she is sticking to the new routine.’

After unveiling the cover art for Woman's World and sharing a video from the shoot, fans were quick to speculate that she had used a weight loss wonder drug – a favorite of celebrities including Sharon Osborne, Scott Disick and Oprah Winfrey – to achieve her new figure.

But the insider shot down such claims, insisting her toned physique is down to working ‘hard.’

‘Her weight loss has nothing to do with any help from Ozempic or weight loss drugs,’ they added. ‘She just worked hard and is eating better than ever.’

Orlando, who shares daughter Daisy Dove, three, with the singer, previously divulged details about his diet and exercise regime, telling GQ he tries to avoid sugar because he is an ‘addict.’

‘I try to have a balanced diet really – greens and proteins,’ he said. ‘Gluten makes me fall asleep.’

Dishing on his workouts, he said he: ‘I try to mix it up. So I walk a lot or I cycle. Or I try to get cardio at a low heart rate, and then try to get a high cardio heart rate a couple of times if I can. I’ve moved away from really heavy weights. I'm thinking more, as I'm in my mid-forties, about longevity.’

He disclosed more details during a bizarre interview with the Sunday Times in 2021 in which he said he is '90 per cent plant-based' and that his first meal consists of ‘porridge, hazelnut milk, cinnamon, vanilla paste, goji berries, a vegan protein powder and a cup of PG Tips.’

He also added that he only eats red meat sporadically because sometimes he will ‘look at a cow and think, that’s the most beautiful thing ever.’

Perry, who has been dating the British actor since 2016 following her divorce from Russell Brand, previously opened up about championing body positivity.

'I know for me, I'm curvy, I'm not sample size, but I represent a lot of people out there,' she told Mashable in 2016. 'I want to be relatable. That's really important to me, while not losing my mind in this weird f***ing human experiment I'm going through.'

She is currently gearing up for the release of her seventh studio album, and first since Smile in August 2020 which received mixed reviews.

She marked the announcement of the first single from the as-of-yet untitled album on Instagram with a picture of herself wearing a tight white bikini, flashing her underboob, and a pair of metallic armored pants.

Kim Petras and Jessica Simpson were among those celebrating the news.

She also shared a selfie-video from what appeared to be the set of the music video showing her in the same outfit lip syncing to the new track.

Lyrics include: ‘Sexy confident. So intelligent. She is Heaven sent. So soft. So strong.’

On Instagram she wrote: 'WOMAN’S WORLD. SONG JULY 11. VIDEO JULY 12. PRE-SAVE + PRE-ORDER. GET READY TO POP OFF.’

The new release comes just under a year since she sold her catalog for $255 million to Litmus Music, and weeks after she bowed out of American Idol. She was a judge on the ABC show from 2018.
