Music mogul Simon Cowell has laughed off reports he gifted his pop protégé Leona Lewis a $5 million mansion after she landed the number one spot in the U.S. Billboard charts.

Singer Lewis became the first British female solo star in over 20 years to top the Billboard Hot 100 chart with her single Bleeding Love last month (Mar08), and her label boss Cowell had reportedly been so delighted with her success in America, he gave her the key to her own Hollywood house.

But multi-millionaire Cowell has dismissed the reports, insisting he has made no exceptions with Lewis, despite her worldwide popularity.

Asked if the rumors were true, he replied, "No! If I did that I'd be broke every time I had a hit."
