Singer Kelly Clarkson has been forced to scrap her U.S. tour due to poor ticket sales. The American Idol winner, who fired her manager this week (begs11Jun07), was due to hit the road next month (Jul07). Clarkson writes on her website: "I can't tell you how much I've been looking forward to getting out there to perform for y'all... It really is disappointing for me to have to tell you that I won't be coming out to tour this summer. "The fact is that touring is just too much too soon. But I promise you that we're going to get back out there as soon as is humanly possible to give you a show that will be even better." Michael Rapino, boss at ticket company LiveNation, adds, "Ticket sales have not been what we anticipated and we came to the realisation that we had bit off more than we could chew. "In the end, we are in the Kelly Clarkson business and for that reason we believe that this decision will only benefit her and her fans in the long run." Clarkson releases her new album My December later this month (Jun07). Fans can get refunds for tickets at the place of purchase.
