Gossip girl question?

you know how in the gossip girl books , serena van der woodsen (blake lively) is supposed to be the most prettiest in the books, but in the tv show, i believe serena vander woodsen is just not as pretty as blair waldorf (leighton meester). Do you agree. Blake Lively looks older than she is, she is actually younger than leighton. Blake's voice is annoying, she can't act and the only reason she got the chanel campaign , was because she is a close friend of karl lagerfeld. While Leighton Meester, she is the face of a vera wang perfume, reebok,missoni, herbal essences and espoir. And leighton meester has 2 movies coming out soon, monte carlo and the oranges. CHECK Out the trailer for monte carlo.
