Katy Perry flaunts her incredibly toned abs in a quirky denim co-ord as she steps out during Paris Fashion Week - after surprise catwalk appearance

Katy Perry was spotted leaving her swanky hotel on Monday, less than 24 hours after her surprise appearance on the Vogue World catwalk amid Paris Fashion Week on Monday.

The songstress , 39, showed no signs of tiredness after partying into the early hours at the bash's afterparty as she emerged from her hotel another busy day.

Katy looked nothing short of sensational in a quirky denim co-ord, yet again opting for a skimpy ensemble after sparking speculation that she could be using Ozempic.

Her outfit featured a cleavage enhancing cropped corset and figure-hugging skirt that boasted cut outs and was adorned with metal hardware. 

The I Kissed a Girl singer completed the look with a spiked denim jacket which she left fall casually from her shoulders.

It comes after Katy went completely nude in a geometric cut-out dress as she walked the star-studded runway at Vogue World Paris on Sunday evening.

The singer made a surprise appearance on the catwalk in the barely-there ensemble and joined a host of celebrities.

She flashed her cleavage in the racy look and covered the rest of her modesty with floral motifs.

Katy strutted around the famed Place Vendôme in front of star-studded guests, wearing towering tie-up heeled boots.

Last year the event was hosted in London, while the year before the Big Apple was the backdrop for the high fashion extravaganza. 

After the catwalk show, Katy changed into a one shoulder gold and silver tasselled dress for the event's after-party, held at Maxim's. 

The pop star was surrounded by fans as she arrived at the event and happily signed autographs before making her way inside.

An array of famous faces took part in the sold-out Vogue World event, celebrating 100 years of fashion and sport in the iconic city.

Katy's trip to Paris comes days after she stripped down to a tiny white bikini to promote her big musical comeback. 

The singer sparked speculation about her weight loss, with some questioning if she  he may have used a weight loss drug to trim down. 

But an insider told DailyMail.com the mother-of-one's new look is the result of adopting her fiancé Orlando Bloom's diet and exercise routine.

This included cutting out processed foods and curbing her alcohol intake.

Former British Vogue editor Edward Enninful was also in attendence

'She loves savoury food, she loves chicken nuggets and sugary food, but recently she has been way more disciplined and has chosen to follow Orlando's diet,' the source revealed. '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.'
