Hire Madonna for Your Party -- C'mon, It's Only $10M

Needless to say, Rihanna was provided the utmost of accommodations, including the presidential suite at the new Ritz-Carlton Moscow, complete with emergency generator and private security detail for her six-hour stay.

Reports surfaced recently in the U.K. that Madonna is in negotiations to make her own command performance in the United Arab Emirates, following what will be one of her most profitable concerts to date in Dubai.

On tour for Live Nation, Madonna is rumored to be considering a performance of her new Hard Candy compilation for an unnamed Dubai-based tycoon who is willing to pay nearly $10 million dollars for the one-night performance.

Should the concert go forward, it would be the most lucrative private performance to date by any professional singer or recording artist.

If you feel the need for a superstar soiree and don't have the budget of an oil tycoon, you still have options. Several U.S. agencies specialize in booking marquee talent for private parties and special events.

Agencies like Universal Attractions in New York (212-582-7575) specialize in celebrity talent booking that include everything from '60s Motown legends to modern-day pop stars in a moment of financial need. Commanding booking fees of around 20% to 40%, most of these companies are no more than private enterprises who contact the artist's management directly. Ongoing relationships allow some companies to specialize in certain artists, although most performers will work through a variety of booking companies.

If your heart belongs to an A-list star, we suggest you be prepared to shell out seven-figure booking fees.

Those who are a bit more industrious may want to save the money of a booking company and have your assistant or party planner do the grunt work and contact the talent management on your own (via WhoRepresents.com), pursuing your greatest star desire and price.

You'll probably be treated like a stalker at first, but provided the right details and prompt payment, we're sure most rock stars are just a price tag away -- just as long as it's a six- to seven-digit number.
