Susan Boyle, whose rollercoaster ride to fame on Britain’s Got Talent captivated millions, does not come cheap. How much does it cost to book the Scottish singing sensation? A mere $15,000 a minute, according to one corporate client. The client was told by Boyle's agent that booking her for three four-minute songs would set him back $190,000. “She's the biggest star to have come out of Britain's Got Talent, so her price to sing reflects that,” a source close to Boyle explained.
