Mischa Barton to guest-star in Gossip Girl?!

so who exactly would she play? she's a bit old to be one of the constance
girls. plus hasnt her poor little rich girl bit been done to hell? i really
like mischa as an actress and i liked her in the oc. i don't think that the oc
is as sophisticated as gossip girl is and as much as i like mischa i don't
think she could play a manhattan upper east side princess to rival the likes
of leighton and blake who rule the screen as blair and serena.
any other comments?

her second worst career move yet then, if she did.

wait!!! i thought that mischa barton was doing us all a favor by giving up
acting??!!

please god, noooooooooooo!!
