If you watch very carefully, you'll see her in another shot that comes earlier in the commercial than the one posted by victoriawinters. It's of the same reading group, with the same woman talking, and KLS is on the right side of the screen, in profile, and out of focus. You'll need to work your pause and frame advance buttons to see it, but it's definitely her.
