Just when you thought Glee couldn't get any more star-studded, they went and added Gwyneth Paltrow to the lineup. The actress is in talks to appear in two episodes as a substitute teacher; not only does she stand in when Mr. Schuester gets sick, but apparently she'll be a love interest as well. Guess it's only fair since Emma's got a new paramour in John Stamos. Hey, at least this will give us a chance to hear Gwyneth's pipes on something other than country tunes. Are you excited about this news?
