#10 Leighton Meester (new entry)
This diamond in the rough hasn't always had it as easy as her character Blair Waldorf, in hit TV teen drama Gossip Girl. She was actually born inside prison walls while her mother served a federal jail sentence for being involved in a drug ring. But the leggy, free-spirited brunette is proud of her parents and her upbringing despite their time spent locked-up.
#5 Blake Lively (up 34 places)
Yes, her name sounds like something a drill instructor might bellow. But the fact this 22-year-old is even on your radar is testament to her perfect Californian looks and body: so far her biggest film role was in The Sisterhood Of The Traveling Pants. Shit. But hold on: she has just been cast as Carol Ferris in the up-coming superhero film Green Lantern, opposite Ryan Reynolds. Which means – nerd alert – she’ll later become the cool villain Star Sapphire. And that means – gay alert – you can now legitimately watch her inGossip Girl as ‘research’.
