As you may know, Tim Gunn is making a cameo apperance on Gossip Girl. You may also know that he had nothing nice to say about Taylor Momsen, at all, while he was there, even calling her "pathetic." See http://www.huffingtonpost.com/2010/09/15/tim-gunn-taylor-momsen-is_n_717534.html
Of course, why would Tim Gunn have anything nice to say about her? At best, Little Miss Momsen is, well, a zombie hooker.
