The rise and fall - and rise of Britney Spears has been heavily documented over the years. First her split from husband Kevin Federline, then wild partying and shaving her head, then the public diva strops, drug abuse claims, a terrible comeback performance and finally the singer lost custody of her children.

However Britney seemed to clean up her act and her last two albums, 'Blackout' and 'Circus', both proved to be a roaring success.
