Katy Perry And Kanye West Hold Adele, Britney Spears Off US Number One

Katy Perry has held onto the US number one spot for the fifth week.

The singer's new single 'ET' featuring Kanye West spent a fifth week at the top of the US Billboard chart.

Perry held off Adele's 'Rolling In The Deep', which is at number two, as well as Britney Spears' new single 'Till The World Ends' at number three.

'ET' has now sold over 300,000 downloads since its release.

The margin of 500 copies between Perry and Adele marks the tightest race for the top spot since Mariah Carey's "All I Want for Christmas Is You" and Eminem's "When I'm Gone", which each sold approximately 41,000 in 2005.

Meanwhile, Katy Perry has spoken candidly about her relationship with Russell Brand.
