Sir Elton John will lead a host of performances at Jeff Bezos and Lauren Sanchez's wedding, sources have told the Mail.
The Rocket Man singer, 78, owns an apartment in Giudecca in Venice, just a short boat ride away from the Bezos wedding events across the cities.
Also set to perform as part of the extravaganza is Lady Gaga, 39.
Elton and Gaga do already have a close friendship - she is godmother to his children - and Jeff and Lauren were said to have personally requested the both of them, says a well-placed source.
The pair have a couple of songs already which they have collaborated together on including Hello Hello and Sine From Above.
It's thought to hire Elton would have cost Bezos around £1million, but perhaps more, according to sources.

The same would be said for Lady Gaga.
On Wednesday night, Jeff and his bride to be Lauren hosted a cocktail party at the Aman hotel.
Clearly lovers of music, they blasted More Than A Woman by the Bee Gees in the garden of the hotel.
They then continued to play tunes like Nina Simone's I'm Feeling Good, Lovely Day by Bill Withers and Brown Eyed Girl by Van Morrison.
After being dropped off by water taxi to the hotel's private jetty, the couple were also joined by around 50 other of their closest guests and friends.
Earlier in the day, in the private garden of the hotel, which is surrounded by a 10ft brick wall, staff could be heard working to erect marquees, ready for a weekend of celebrations.
The Mail revealed that Bezos has hired out the hotel, which is the same that George and Amal Clooney used for their wedding, from Wednesday for 48 guests.
Huge security staff also surrounded the property, around five or six men at each entrance.

Already a local, Sir Elton bought his one bedroom property in Venice in 2004, and it has views across the water of San Marco as well as huge gothic windows out of the front.
It's a short walk away from the famous Hotel Cipriani, the only hotel Brad Pitt will stay in when he visits Venice.
Sources told the Mail 30 guests of the Bezos wedding are staying at £2,700 a night Hotel Cipriani.
Staff of Bezos visited the five-star, private hotel at the beginning of the week, to check security measures as well as fly a drone over the opposite island San Giorgio, where one of the wedding events is going to be held.
A huge marquee has been erected in the private gardens on the island and security, who are all ex-marines, have done multiple site visits.
On Thursday, security men could be seen surrounding the island, marking one every few metres. Even at the back of the island where there is a wooded area.
A source told the Mail earlier this week: 'A function is happening on the island, in the private gardens. They've closed parts of it for days and days and you can only hire that out if you're very very rich.'
The star-studded guest list is said to include Leonardo DiCaprio, Mick Jagger, Oprah Winfrey, Orlando Bloom, Tom Brady and Kim Kardashian.

Other high-profile guests such as US First Daughter Ivanka Trump and her family have already arrived.
The couple are currently being plagued by protesters across the city who are furious the needs of local residents are allegedly being sidelined to make way for wealthy tourists.
Bezos is worth around $224.6 billion and is thought to be spending tens of millions on his wedding.
'If you can rent Venice for your wedding, you can pay more tax,' one gigantic banner read in St. Mark's Square.
Greenpeace and the UK-based collective Everyone Hates Elon have joined protests in Venice attempting to disrupt, or even prevent, the planned wedding celebrations of Amazon founder Bezos this week.
'Jeff Bezos is the second-richest man in the world yet is reported to pay a 1.1 percent true tax rate,'
the two groups said in a joint statement. 'The multi-million-dollar wedding is reportedly happening over three days, with the wedding ring alone worth as much as $5million.'
Venice mayor Luigi Brugnaro and regional governor Luca Zaia have spoken out in favor of the nuptials, which have been dubbed, 'the wedding of the century,' pointing out that the celebrations are expected to bring $23-34million to local businesses.
'This is a city that handles 150,000 people a day,'
Zaia told Italian daily Corriere della Sera. 'George Clooney, François-Henri Pinault and Salma Hayek, Alexandre Arnault, Elton John and many others got married here.'
