The prince will be supported by a constellation of superstars including Madonna, Orlando Bloom, Pierce Brosnan, Gerald Butler, Hugh Grant, Andy Garcia, Goldie Hawn, Diane Lane, Eva Longoria, Adrien Brody, Robin Thicke and Karlie Kloss to name but a few.

The Queen of Pop is also offering a "Portrait sitting with legendary photographer Steven Klein, art directed by Madonna" which will take place in New York, and an experience to "Join Madonna in her recording studio in London and preview songs from her upcoming album", as well as several works of art.

Other celebs have also put their best foot forward including Prince Albert II himself who will host a lucky bidder at the next Monaco Formula E Prix Championship, legendary surfer Kelly Slater who will take someone surfing at his private ranch in California, actor Andy Garcia who will play golf with a charitable patron at the Lakeside Club in Los Angeles, or supermodel Toni Garrn who has offered a private behind the scenes tour of the Paris Fashion Week.
