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.

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.
