Vanessa Abrams from Gossip Girl. I watch every week and I don’t particularly like the show but I never miss an episode because of her.
Incidentally, I met her at a show I was working a month ago (Much Music Video Awards) and she was a guest (I work in the Art Department). I stood beside her backstage for about 15 minutes while we watched the proceedings and I made small talk with her but couldn’t come up with anything remotely interesting to say. It was not my finest hour, to be sure. (she seemed very pleasant, incidentally, and is even more beautiful in person)
