Katy Perry has become the first artist to remain in the Billboard Hot 100's top ten for 52 consecutive weeks.

Since the release of her hit 'California Gurls' last May, at least one of Perry's tracks - including 'Teenage Dream', 'Firework' and 'E.T.' - has stayed within the top ten.

Her second album Teenage Dream has become just the ninth in US chart history to produce four number one singles.

The 26-year-old performer has also managed to pass the 3 million digital sales mark with her latest US number one hit 'E.T.', which features guest vocals from Kanye West.

The accomplishment means that Perry has managed to sell over 3 million copies of her last six singles, making her the first artist to do so in digital sales history.
