Britney Spears is on course to top the US Billboard album chart after selling over two hundred thousand copies of her new album in a day.

Spears' 'Circus', her follow-up to 2007's 'Blackout', went on sale in the US on Tuesday (December 2nd), her 27th birthday.

Sales figures indicate that the album could sell in excess of 450,000 copies by the end of the first week.

Kanye West is the current US number one with '808s and Heartbreak'.

As previously reported, Spears is unlikely to match the feat in the UK, where she is trailing Take That's album, 'The Circus', by over one hundred thousand copies.

Take That sold 133,000 copies of the album on Monday alone, making it the fastest selling record of 2008.
