Britney Spears has emerged as the biggest- selling female artist of this century as the singer's records have outsold all of her counterparts.
Britney, who has even beaten Madonna , has been more successful than any of her female peers in the past five years.
Even big-name stars including Kylie, Dido, Beyonce, Celine Dion and Whitney Houston have been overshadowed by Britney's soaring sales.
'It really is extraordinary. Britney and everyone here are thrilled. To become the biggest selling female artist of the past five years was amazing, but to outsell Madonna over the past half a decade is beyond our wildest dreams. It just goes to show what a musical force Britney is,' a spokesperson from Jive Records, was quoted by the Daily Mail, as saying.
