OMG OMG OMG! She has been chosen!! Heck yeah!
Well first off some information on the actress...
Name: Lily Collins
"In December 2010 it was announced that Lily won the role and will star as Clary Fray in the popular young adult novels Mortal Instruments which are currently in the process of being made hopefully into a successful movie franchise which spans 4 books written by Cassandra Clare.
Lily’s role will revolve around her character Clary who is a 16 year old shadow hunter that is around 5 feet tall with red wavy hair who is physically enhanced with angel blood that has mystical powers to seek out demons. Filming locations, plots, & etc are unknown at this time due to that it is early in production."

What Cassandra has to say about this:
"She is completely adorable and looks right for Clary to me.
ETA: Look, no actor or actress is going to look perfect or right to absolutely everyone for the part. Keep in mind *I* don't choose the actors or actresses who star in the movie — I have to trust the vision of the producers and director, and I do. I hope you can be optimistic too, but if not, super-nasty comments about Lily are going to be deleted."
Information from Cassandra's Blog.
I agree with Cassandra. I think the actress is adorable and can pull it off! Now speculation about Jace's actor are about to start. Who will it be... Someone who is hot, dark, and mysterious no doubt. Do not pick Robert Pattison pleeaasseee. I like him lots, but I think Jace deserves his own original one of a kind actor.
Here are more pictures of the girl:
Let's all hope that by the end of this movie endeavour we will all be rejoicing like her in this last picture. Oh yes, she is also a model, she is pretty enough so that doesn't surprise me.
