Mariah Carey and Tom Jones will each earn £1 million to open a new resort.
The 39-year-old diva and the 68-year-old Welsh singer will each sing a one-hour set to open an exclusive £926 million development in Turkey – said to be the most expensive resort in Europe.
The Mardan Resort in Antalya is owned by Russian tycoon Telman Ismailov – who also once reportedly paid Jennifer Lopez £1 million to sing 'Happy Birthday’ to him - who is determined for the grand unveiling of his hotel to be a breathtaking affair.
A source close to the tycoon said: 'Telman is not a man who hesitates when it comes to throwing big parties.
'He wants the opening of the hotel to be a major event and insisted Tom and Mariah be booked to perform, no matter what the cost.'
The Mardan Resort features five acres of fresh water swimming pools and has a sunken aquarium stocked with over 2,000 fish as its centrepiece.
The hotel boasts 560 rooms, and the best suite costs £13,000-a-night. Many stars, including Sharon Stone and Sir Paul McCartney, have also been invited to attend the opening on May 23.
