If you refer to Jacqueline King's post on her facebook page with a link to the Star Trek trailer and her commenting "Getting excited..." (from April 17), someone asks her personally the same question you were looking to answer. She comments: "The blond is Jodi Jonston" (link, here: https://www.facebook.com/permalink.php?story_fbid=5686193865...)

Anyways, kudos on the work - but it was easy as that.
