'Circus' is set to hit stores on December 2 - Britney's 27th birthday - with the star set to embark on a world tour to promote it next year.

The first single from the LP, 'Womanizer', has already caused a storm in the US, after topping the Billboard Hot 100 chart when downloads of the track exceeded 286,000 in its first week of release.

The success of the single makes it the first number one song for Britney in the US since her 1999 track 'Baby One More Time'.

Along with the artwork, Britney has also released a full tracklisting for 'Circus' and has confirmed the next single will be the title track.

Meanwhile, Simon Cowell has confirmed Britney will appear on UK TV talent show 'The X Factor' on November 15.

He said: "I'm really excited about it, because she's got her act together now and the new record's terrific.

"She's come back from a very dark place and is a great artist."

Simon believes Britney could become "the biggest star in the world" after getting her life back on track following her public breakdown earlier this year.
