Katy donned the loose-fitting satin top with a black jumper wrapped around her waist. 

She wore a slogan hat that read 'I [heart] Paris' as she roamed around the French city and mingled with the bride and groom fans.

The hitmaker displayed her toned legs and elevated her frame slightly with tiny black court heels.

On Monday, Katy wowed in a spiky denim lace-up corset and maxi skirt co-ord, which was covered in holes.

She debuted the funky look fewer than 24 hours after her surprise appearance on the Vogue World catwalk for Paris Fashion Week.

Katy went completely nude in a geometric cut-out dress as she walked the star-studded runway on Sunday evening.

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

In 2023, Vogue World took place in London, while the year before the Big Apple was the backdrop for the high fashion extravaganza.

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, showcased by the photo, and some questioned whether she used Ozempic.

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

The routine includes cutting out processed foods and curbing her alcohol intake. 

'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.'

Katy and Orlando began dating in 2016, split in 2017, reunited in 2018, and got engaged on Valentine's Day 2019.

Their daughter Daisy Dove was born in August 2020 and she has a brother, Flyn, 13, from Orlando's marriage to Miranda Kerr.

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.'

On July 11, Katy will release Woman's World, the former American Idol judge's first single since 2021. The song will be the first from Katy's upcoming seventh studio album.
