So, here's a weird thing: Apparently, there are people who make a (blog) living out of tracking down the attractive people in ads and revealing their names and professional information.
Yep. WhoIsThatHotAdGirl.Tumblr.com. It's a thing that exists—and of course it would, in this day and age, considering that there is a Tumblr for literally anything your weird, deviant heart desires (as one of our poor, unnamed staffers learned one day, during an innocent search for attractive men and kilts.)
In all seriousness, they're doing a service (to an extent), as they dig up contact information, demo reels, and past work for women who may not otherwise be heard from very often—even if they are doing it to aid in providing fantasy material for people on the Internet.
