Singer Lily Allen is sweet but also extremely sour. What more can you expect from a babe who wrote the line, "When I see you cry, it makes me smile"? Pert and perky in every way, with a heavy fringe of dark hair over her sexy Bambi eyes, Lily became an instant sensation when she posted some of her songs on her MySpace page. Millions of downloads and a record deal later, she's become one of the most recognizable pop stars of the decade, with her sugar-coated voice delivering devilishly naughty lyrics on her albums Alright, Still and It's Not You, It's Me. And fun-loving Lily is just as known for her offstage antics—she's regularly snapped attacking paparazzi, getting into drunken fights at awards shows, and sunbathing topless. She's even got a third nipple and will graciously show it to anyone who asks! But listen, Lily, if you really want to make us "Smile," get naked in a movie . . . your chart toppers are #1 with us!
