"You can not compare Britney with Lady Gaga. You are putting Lady Gaga at the same level of Britney Spears? I really cannot believe it. Lady Gaga is good, but she’s a new artist, Britney Spears is a legend. They are two different artists, two forms of entertainment but very different, it's like comparing Picasso to Dali." British singer Lily Allen is a firm fan of pop star BRITNEY SPEARS.
