Katy Perry has become the first artist in US chart history to spend an entire year in the top 10.

Four of her singles have been in the Billboard Hot 100 chart separately for 52 weeks in a row.

Swedish group Ace of Base held the previous record with a 48-week run with All That She Wants, The Sign and Don't Turn Around between 1993 and 1994.

In April, Perry became only the ninth artist in US history to score four number 1 singles from the same album.

E.T. (featuring Kanye West) went down to number two in the US chart this week after spending five weeks at the top.

California Gurls, Teenage Dream and Firework also all spent time in the top 10 over the past year.

Currently on a world tour, Perry will play a series of concerts across the UK in October and November.
