The latest addition to the cast of "Gossip Girl" is Mädchen Amick, who will be playing the role of Catherine Mason, a new and older love interest (a "SOW"... Sexy Older Woman) for Nate Archibald (played by Chace Crawford).

Mädchen Amick appeared in the horror film "Sleepwalkers" and was the best thing in it. This Stephen King horror also featured cameos by the writer himself alongside John Landis, Joe Dante, Clive Barker, Tobe Hooper and Luke Skywalker Mark Hamill.
