Lady GaGa has scored a fifth week on top of the U.S. pop charts but Katy Perry is making history in the Digital Songs countdown.
Gaga's Born This Way debuted at number one last month (Feb11) and still holds the top spot on the Billboard Hot 100 ahead of Cee Lo Green's F**k You and Perry's E.T., which becomes the pop star's fourth Digital Songs number one release from her Teenage Dream album - a new chart record.
Gwyneth Paltrow's rendition of Stevie Nicks' Landslide with the cast of Glee is the new chart's highest debut at 23.
