YA Higheway - Choose your narrator?

Road Trip Wednesday is a ‘Blog Carnival,’ from YA Highway where each week there is a writing- or reading-related question for us to answer. Check out YA Highway to follow along with everyone who participates. :-)

This Week's Topic:
Some audiobooks are read by celebrities. Most recently, Cassandra Clare's CITY OF FALLEN ANGELS was partly read by Ed Westwick of Gossip Girl.

So, if you got to choose a celebrity narrator for the audio book of your WIP or your favorite novel, who would it be and why?

Since I really don't have a clue as to who would have the right voice for my book, I'll go with the names of some of my favorite actors. My current WIP is from the female POV, so my choices would be:

Rachel McAdams (she sort of has the look of my character, too, which is nice):

Kate Beckinsale (in an American accent, of course):

They are both beautiful and have great screen presence so maybe their voice would fit for an audio book, too. 

What do you think?
