Katy Perry Set To perform at Billionaire Anant Ambani’s Pre-Wedding.

Katy Perry is set to make millions from performing at a pre-wedding for one of the world’s richest men.

The 39-year-old pop star is jetting to Cannes in the south of France to perform a short set for Anant Ambani and his bride Radhika Merchant.

A source told The Sun newspaper: “They have invited 800 guests who are currently on a space-themed cruise around Europe, with stops in Barcelona and Genoa.

“It will arrive in Cannes on Friday for the big bash, which will be at a £40 million estate. The party itself will only last five hours but Katy will headline it, with a DJ also being flown in as part of the top-tier entertainment. Afterward, guests will watch a huge fireworks display from a small armada of ships waiting in the Bay of Cannes.”

The loved-up couple will officially tie the knot in July, but they’re determined to stage a memorable pre-wedding event.

The insider added: “When they say there’s been no expense spared, they mean it.”
