Katy Perry breaks US Billboard chart record

 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.

The "California Gurl" announced via Facebook (and then tweeted) that she's all set to kick off her California Dreams World Tour.

Perry has planned 41 dates for the North American leg of the outing, beginning in Atlanta on June 7. The singer will hit the road throughout the U.S. and Canada before wrapping up in her hometown, Santa Barbara, California in August.

 Marina and the Diamonds and dance singer Robyn will also join Perry, who made a special live appearance via Facebook on Thursday (January 19) to announce the tour. Before the North American dates get under way, though, Katy will head to Lisbon in Portugal where she'll hit the stage on February 20; Perry will then travel throughout Europe, the U.K., Australia and Japan.

The pop star plans to continue interacting with her fans through a variety of social media networks, including Facebook's Places function, which will allow concertgoers to get special treats when they check into certain concert venues. Fans will also be encouraged to submit their own photos of the show through Twitter, which will be incorporated into the live show and Perry's official website.
