Teenager Lorde has scored a TransAtlantic double after rocketing to the top of the U.K. singles chart with Royals. The 16 year old becomes the youngest artist to enter the top 40 at number one since 1998, when 15-year-old Billie Piper hit the top spot with Because We Want To. New Zealand-born Lorde's hit single has beaten TV talent show winner James Arthur to number one; his single, You're Nobody 'Til Somebody Loves You, enters at two, while last week's chart-topper, One Republic's Counting Stars slides to three on the new countdown. Lorde scored a fourth week at the top of America's Billboard Hot 100 singles chart on Wednesday (23Oct13). Girl power also rules at the top of the U.K. albums chart as Katy Perry's new release Prism debuts at number one, just ahead of James Blunt's Moon Landing and last week's chart-topper from John Newman, Tribute.
