Susan Boyle’s debut album I Dreamed a Dream has topped the US chart.

The Britain’s Got Talent singer shifted just over 700,000 copies of the record, debuting at No 1.

Reports suggest that amount of sales not only gives her the best first-week sales of 2009, but also the best-selling album debut by a woman in the Billboard SoundScan era.

Susan also reached the number one spot in the UK charts.
