Katy Perry exudes glamour in a busty metallic silver gown as she performs at billionaire Anant Ambani’s pre-wedding bash in Cannes

Katy Perry oozed glamor in a metallic dress as she put on a breathtaking performance at billionaire Anant Ambani’s pre-wedding bash in Cannes on Monday.

The 39-year-old singer was booked to perform at a masquerade ball for the son of India’s richest man and his bride Radhika Merchant.

As if Katy wasn’t enough, Anant booked Italian tenor Andrea Bocelli to perform at his star-studded prenuptials.

Anant, 29, is the son of Reliance Industries chairman Mukesh Ambani, who is Asia’s richest person, worth more than $114 billion, according to Forbes.

Katy and Andrea are following in the footsteps of Rhianna and Beyoncé, who have been paid eye-watering fees to perform for the billionaire in the past.

And shielding her nerves during the multi-million pound performance, Katy appeared in good spirits as she graced the stage in front of a series of celebrity guests.

She oozed glamor in a stunning silver dress and styled her hair in loose curls as she danced across the stage.

The hitmaker reportedly sang her favorite hits for the bride, groom and their 800 guests.

Last week a source told The Sun: ‘They have invited 800 guests who are currently on a space cruise around Europe, with stops in Barcelona and Genoa.

‘He will arrive in Cannes on Friday for the big bash, which will take place at a £40million estate. The party itself will only last five hours, but Katy will be the headliner, with a DJ also being flown in as part of the top entertainment.

‘Afterwards, guests can watch a huge fireworks display from a small fleet of ships waiting in the Bay of Cannes. When they say no expense has been spared, they really mean it.’

The dashing Andrea looked incredibly dapper in a light blue suit jacket, paired with a navy waistcoat and trousers.

For his daughter’s wedding in 2018, the groom’s father Mukesh reportedly paid Beyoncé, 42, $6 million to perform a private concert for guests.

While MailOnline has been told that Rihanna recently raked in £5 million ($6.33 million) for her performance at another pre-wedding party for Anant and Radhika in March.

The previous pre-wedding blowout cost as much as £120 million, sources told MailOnline, in stark contrast to the nearby slums just a stone’s throw away, where some of the world’s poorest work up to 17 hours for just $5 a day.

Katy took to Instagram on Monday while in Cannes to show off a series of photos from her luxury trip.

Wearing nothing but a tiny thong bikini and stiletto heels, the singer kicked up her feet as she posed on the balcony of the Hôtel du Cap-Eden-Roc in Antibes.

After the lavish party, Perry took to Instagram to share snaps and a TikTok clip of herself enjoying the picturesque sunset in her bikini and walking around in a sheer cover-up set adorned with iridescent sequins.

In addition to a caption with nothing but an orange heart emoji, she also enjoys a can of De Soi, a non-alcoholic aperitif brand she co-founded in January 2022.

In photos and videos shared by the Fireworks hitmaker and her makeup artist Michael Anthony on Monday, the bikini-clad superstar was captured looking down from the balcony of the lavish hotel.

She also donned a sheer sequined blouse, which exposed her toned midriff, and the matching midi skirt over her swimsuit for close-up photos outside the hotel.

To the tune of her 2010 hit single Teenage Dream from her studio album of the same name, she was seen wearing only a bikini as she flipped her hair up and sipped her drink.

She later threw on the crop top and skirt over her swimsuit.

The clip later featured her, drink in hand, walking along a sweeping walkway and grand staircase leading from the seafront to the luxurious five-star hotel.

For her sultry photo series, she let her jet black locks hang down in soft beach waves that were swept to the side.

To bring out the pink iridescence of the sequins on her cover-up, she wore a matching, monochrome makeup look with a glossy, light fuchsia pout.

She dressed up with gold bracelets, dangling earrings and a sparkling tennis necklace.

She also wore stacks of statement rings, including the massive engagement ring that her fiancé Orlando Bloom proposed to her in 2019.
